How to Calculate and Solve for the Length of a Side and Perimeter of a Pentagon | Nickzom Calculator

The image above is a pentagon.

To compute the perimeter of a pentagon, one essential parameter is needed and this parameter is length of side (a).

The formula for calculating the perimeter of a pentagon:

P = 5a

Where;
P = Perimeter of the pentagon
a = length of side

Let’s solve an example;
Find the perimeter of a pentagon when the length of side (a) is 25 cm.

This implies that;
a = length of side = 25 cm

P = 5a
P = 5 x 25
P = 125

Therefore, the perimeter of the pentagon is 125 cm.

Calculating the length of side using the perimeter of the pentagon.

a = P / 5

Where;
a = Length of side
P = Perimeter of the pentagon

Let’s solve an example;
Given that the area of the pentagon is 250 cm. Find the length of side?

This implies that;
P = Perimeter of the pentagon = 250 cm

a = P / 5
a = 250 / 5
a = 50

Therefore, the length of side (a) is 50 cm.
