Answer 2

Given: The perimeter of a regular pentagon is $115$cm.

We have to find the length of each side of a regular pentagon.

As we know that the formula is used to calculate the perimeter of a regular pentagon is: $P=5a$

Where

a = A side of a regular pentagon.

We are solving in the following way:

We have,

The perimeter of a regular pentagon is $115$cm.

So, the length of each side of a regular pentagon will be:

$P=5a$

$=>115=5a\\\\=>\frac{115}{5} =a\\\\=>a=23$

Hence, the length of each side of a regular pentagon is $23$cm.
