Surface Area of a Rectangle Calculator
Possessing a length and a breadth is the main characteristic of any two-dimensional figure. The TSA of a rectangle is simply defined as the value of the entire region occupied by a given rectangle. It is measured in square units like centimetres, square meters and the likes of them. You multiply the length and the width of a rectangle together to get the total area covered.
How To Find The Surface Area Of A Rectangle
Below is a step by step guide showing the formula.
First Step: Determine the dimensions of the rectangle. Know the length and the breadth (also known as the width) of the rectangle.
Second Step: Multiply the length of the rectangle by the width. That is L X W , where W is the width while L is the length of the rectangle.
Third Step: The result you get is your answer. Present it as the total area of the rectangle.
At this point, it is worthwhile to note that a square shape is also a type of rectangle but all of its sides are equal unlike a rectangle whose length is unequal with its width.
How To Find The Area Of A Square
First Step: Determine the length of the square.
Second Step: Now multiply the length of the square by the length itself. Thus, L X L = L². The L represents the length of each side of the square.
Surface area of a Rectangle Example
Question One: If the length of a rectangle is 8 cm while the breadth 4 cm, calculate the surface area of the rectangle in units and present your answer showing all workings.
Solution: The formula for the area of a rectangle is L X W
Therefore, Area Of Rectangle = 8 x 4 cm²
Thus, Area Of Rectangle = 32 cm²
Question Two: Find the total area occupied by a rectangular wall given the length as 20 cm and width as 5 cm.
Solution: Area of A Rectangle Formula = L X W
Area Of The Rectangular Wall = 20 x 5 cm²
Therefore, Area Of The Rectangular Wall = 100 cm²
The Surface area of a rectangle equation is given as L X B where L is the length of the rectangular figure while B is the breadth or width of the shape.
However, the total surface area of a rectangle calculator is the ideal tool for you to use when determining the total surface area of a rectangle considering its width and length. This post aims at explaining in full the surface area of a rectangular shape, the practical equation, how to find the surface area of a rectangle among many other questions closely related to this context.
Surface Area Of A Rectangle Formula
As already stated earlier, a rectangle is a closed figure or shape which has four sides – the opposite sides being equal to each other. From this, we can say that two sides or rather, the two dimensions of a rectangle which are enough to describe the shape includes the length (also known as the height) and the width (which can also be referred to as the breadth).
When looking for the surface area of any given rectangle, the equation is derived as follows:
Area Of Rectangle (AOR) = L (Length) × W (Width)
Hence, AOR = L x W
AOR is the surface area of the rectangle
L is the length of the rectangle. Usually, it is often described as the longest side of the rectangle.
W stands for the width or breadth of the rectangle. Most often, this is always the shortest side of the rectangle.
Square meters (sq. m) or meter square m² are the SI units for presenting the area of a rectangle. Also, the imperial units for representing the area of a rectangle are sq ft (that is square feet) or ft². Before you proceed to calculate the area of any given rectangle, always make sure that the width and length of the shape are both expressed in the same units of measurement so as to arrive at an accurate answer.
Take for instance, a rectangular wall with a length of 15 m which is 4 meters wide (the breadth) will definitely have as total surface area of 15 m x 4 m = 60 m².
Worthy of note is the fact that the rectangle being a 2D geometric representation, it is not enough to refer to its total surface area as the area.
How to find surface area of a rectangle
You need to know the actual length and width dimensions of a rectangle before you can be able to proceed with calculating the surface area of a rectangle. This is a prerequisite factor.
Once the breadth and length are know, the next thing to do is to convert them into the same unit of measurement. Thus, both of them must be measured in the same unit for accuracy of answers. Giving an instance, if the length of a rectangle is 5 m and width of the rectangle is 2 ft, you do not start calculating expressly. First, you need to convert both sides either to meters (m) or feet (ft).
When you have achieved this, you can now go on to multiply the length and width together in order to arrive at the area of the rectangle in corresponding units. Double-check your answer by doing a step by step check on your calculations so as to ensure accuracy of you final result.
How do I calculate the area of A Television Screen
Most screens of monitors bear a rectangular shape. If you want to calculate the area of the screen of your monitor, then you have to follow these simple steps outlined below:
Step 1: Get the measurements of your monitor screen. You can do this by using a measuring scale to find out the length and width dimensions of your monitor. An alternative way of knowing the length and width of your monitor screen is by taking a closer look at the product description enclosed inside the pack.
Step 2: Now that you know the correct dimensions of your monitor screen, go ahead to multiply the width and the length together so as to obtain the total surface area of your monitor screen.
Step 3: The result you get from the above step is your final and accurate answer. You can now be happy having discovered the total area of your monitor screen.
How many acres Make one hectare
By standard rule, every hectare is made up of 2.471 acres. We can proceed from this to further explain that acre is a unit of land which is estimated to be roughly equal to 4047 square meters (sq m). Again, 10,000 square meters makes up a hectare. Popularly, land sizes are measure in hectares, acres and square meters.
