The image above represents a square.
To compute the area of a square requires one essential parameter which is the length of one side of a square.
The formula for computing the area of a square is:
A = l2
A = Area of a Square
l = Length of one side of a Square
Let’s solve an example
Find the area of a square which has a length of 6 ft.
This implies that:
l = length of one side of a square = 6
A = l2
A = 62
A = 6 x 6
A = 36
Therefore, the area of the square is 36 ft2.
Calculating the Length of a Square when Area is Given
The formula is l = √[A]
A = Area of a square
l = Length of a square
Let’s solve an example:
Find the length of a square where the area of a square is 81 ft2.
This implies that;
A = Area of a square = 81 ft2
l = √[A]
l = √
l = 9
Therefore, the length of the square is 9 ft.
