The image above is a hexagon.

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

The formula for calculating the perimeter of a pentagon:

P = 6a

Where;

P = Perimeter of the hexagon

a = length of side

Let’s solve an example;

Find the perimeter of a hexagon when the length of side is 15 cm.

This implies that;

a = length of side = 15 cm

P = 6a

P = 6 x 15

P = 90

Therefore, the **perimeter of the hexagon** is **90 cm.**

**Calculating the length of side (a) using the Perimeter of the hexagon.**

a = ^{P} / _{6}

Where;

a = length of side

P = Perimeter of the hexagon

Let’s solve an example;

Find the length of side when the perimeter of the hexagon is 120 cm.

This implies that;

P = Perimeter of the hexagon = 120 cm

a = ^{P} / _{6}

a = ^{120} / _{6}

a = 20

Therefore, the** length of side (a)** is **20 cm.**
