**Formula Of Area Of A Rectangle**

This article is all about the formula for area of a rectangle, what is the formula of area of a rectangle, area of a rectangle formula class 7, perimeter and area of rectangle, area of rectangle proof and lots more.

**What Is The Formula Of Area Of A Rectangle**

Formula For Area Of A Rectangle – The area of a rectangle is that whole region bordered by the 4 sides of a rectangular figure. The area of a rectangle is equal to the product of its length and breadth (also known as Width). If you are asked to find the area of a rectangle whose length is 13 and the width is 6, then your area of a rectangle worksheet should be as follows:

Formula For Area Of A Rectangle = L x B

Area Of Rectangle = 13 x 6

Therefore, Area Of Rectangle = 78 square units

From the above work out, you can see that the area of a rectangle is calculated by multiplying the length and the width dimensions together. You can also use an area of a rectangle calculator to more quicker and accurate solutions.

**Formula For Area Of A Rectangle**

This can be defined as the total space occupied by a rectangle which can be easily derived by multiplying the width and the length together. That is the Formula For Area Of A Rectangle.

**Write An Algorithm To Find The Area Of A Rectangle**

The formula for calculating the area of a rectangle is given below:

Formula For Area Of A Rectangle = Length Of The Rectangle x Width Of The Rectangle

AOR = L x W

**What Is The Percentage Increase In The Area Of A Rectangle**

The percentage increase in the area of a rectangle can be defined as the rate at which the total region covered by a given rectangular figure extends as a result of increase in its length and width dimensions.

As the breadth of a rectangle widens and the length gets longer, the area of the rectangle also increases. Thus, this percentage increase in area aims at determining the extent to which the area of a rectangle adds up as a result of increase in the dimensions. We can explain this with an example below:

**Question:** What is the percentage increase in the area of a rectangle if there is a 20 percent increase on the respective values of its length and width (the sides)?

**Solution:** Let the length of the rectangle be called “l” and the width of the rectangle be known as “w”.

Formula For Area Of A Rectangle = l x w

Before the increment in the dimensions by 20%, the length and width of the rectangle were 100% complete. Thus we can derive the following equation below:

Formula For Area Of A Rectangle = 100% l x 100% w

To show the effect of the 20% increment, the equation can be written as follows:

Area Of Rectangle = (100% + 20%) l x (100% + 20%) w

Area Of Rectangle = 120 % l x 120% w

Area Of Rectangle = (120 ÷ 100) l x (120 ÷ 100) w

Area Of Rectangle = 1.2 l x 1.2 w

Area Of Rectangle = 1.44 lw

Area Of Rectangle = 144% lw

Percentage Increase In The Area Of The Rectangle = 144% lw – 100% lw

Percentage Increase In The Area Of The Rectangle = 44%

The percentage increase in the area of a rectangle, if each of its sides is increased by 20% is: 44%

**The Formula To Calculate Area Of A Rectangle Is**

Formula For Finding Area Of Rectangle = l x b

Where;

l = The length of the rectangle. It depicts how long the side of a rectangle is.

b = The breadth of the rectangle. This can also be referred to as the width of the rectangle. It measures how wide the side of a rectangle is.

**Write A C Program To Compute Area Of A Rectangle**

Given Below is a standard C Program for calculating the area of a rectangle whose width is 7 cm and the height 8 cm.

C Program

#include <stdio.h>

int main()

{

int width=7;

int height=8;

int area=width*height;

printf(“Area of the rectangle=%d”,area);

}

Area of the rectangle = 56

A plain figure bearing 2 adjacent sides whose lengths are equal is known as a rectangle. The Area of any given rectangle can be defined as how much space which the rectangle occupies. The 4 angles contained in a rectangle are equal to each other. Note that 4 similar squares can be carved out of any rectangle. The each of the 4 interior angles present in a rectangle measures 90 degrees.

Thus, one can describe the area of a rectangle as the total number of square units it will take to fully fill up a rectangle. Hence, the Formula for calculating the area of a rectangle is given as:

Formula For Area Of A Rectangle (A) = L x W

Where,

- A represents the Area of the rectangle
- L represents the Length the of the rectangle
- W stands for the Width of the rectangle

Using these Algorithms above, you can calculate the area of any rectangle following the steps below:

- Determine the width of the rectangle.
- Determine the Height of the rectangle.
- Now proceed to Calculate the area of the rectangle by multiplying the length and width of the rectangle.
- Present you answer in square units.

**What Is The Area Of A Rectangle ABCD? **

Area of Rectangle with 4 sides ABCD where A and C are the lengths, B and D are the widths can be given as follows:

Formula For Area Of A Rectangle = A x B

Area of Rectangle = A x D

Area of Rectangle = C x B

Area of Rectangle = C x D

This is so because the 2 lengths and 2 widths are equal to each other respectively.

**Area Of Rectangle Formula Class 7**

The area of a rectangle remains the same as long as the length and width of the rectangle does not change. Once these dimensions changes, there will be a corresponding percentage increase in the area of the rectangle.

How to get the area of a rectangle – use the value of the length of rectangle to multiply the value of the width and you will arrive at your answer. Thus A = L x W in square meters.

How do you find the area of a rectangle? You use the area of a rectangle formula given as A = L (length) x W (width) determine the area of any rectangular surface.

Surface area of a rectangle formula is given as SA = Length x Width

Surface area of a rectangle calculator is an online calculator used in calculating the area of any given rectangle with known length and width dimensions. It is usually and automatic mathematics calculator.

To write the formula of area of a rectangle multiply the width of a rectangle with its length to have Area of rectangle = Width x Length

What is the formula for area of a rectangle? The formula of a rectangle is A = Length x Width

What is the change in the area of a rectangle? The percentage increase in area of a rectangle can be defined as the extent to which the area of a plain rectangular figure increases as a result of corresponding increase in its length and width. On the contrary, the percentage decrease in area of a rectangle can be defined as the extent to which the area of a plain rectangular figure reduces as a result of corresponding decrease in its length and width

Area of a rectangle is given by multiplying the width and length of a rectangle.

Area of a rectangle definition can be given as the total space covered by a plain rectangular shape.

The Equation for area of a rectangle is AOR = H x W where AOR stands for the area of the rectangle, H is the height or length of the rectangle and W is the width of breadth of the rectangle. That is how to derive the Formula For Area Of A Rectangle as well as area of a rectangle equation.

The formula to calculate the area of a rectangle is length x breadth in square units.

Formula for the area of a rectangle is A = L x W where A is the area of the rectangle, L is the length or height of the rectangle while W is the width of the rectangle.

The area of a rectangle is expressed in square units.

The area of a rectangle is the product of its length and width.

The formula to find the area of a rectangle is the length multiplied by the width presenting the final answer in square units.

The width in area of a rectangle is also known as the breadth. It measures how wide a rectangle is.
