How to Calculate and Solve for the Perimeter and Length of a Square | The Calculator Encyclopedia

The image above represents a square.
To compute the perimeter of a square requires one essential parameter which is the length of one side of a square.

The formula for computing the perimeter of a square is:

P = 4 x l

Where:
P = Perimeter of a Square
l = Length of one side of a Square

Let’s solve an example
Find the perimeter of a square which has a length of 10 m.

This implies that:
l = length of one side of a square = 10

P = 4 x l
P = 4 x 10
P = 40

Therefore, the perimeter of the square is 40 m.

Calculating the Length of a Square when Perimeter is Given

The formula is l = p / 4

Where;
P = Perimeter of a square
l = Length of a square

Let’s solve an example:
Find the length of a square where the perimeter of a square is 100 m.

This implies that;
P = Perimeter of a square = 100 m

l = p / 4
l = 100 / 4
l = 25

Therefore, the length of the square is 25 m.
