Question

The Pentagon shown is a regular pentagon, so each side has the same length. The perimeter of the pentagon is 62.5 centimeters. What is the value of x.

Answer 1

Let one side be x.

In the regular pentagon:

Perimeter = 5 × side

=> 62.5 cm = 5x

=> 62.5cm/5 = x

=> 12.5 cm = x

So, 1 side is of length 12.5 cm
