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.**
