# Perimeter of Hexagon Formula

In geometry, a hexagon is said to the polygon which has six equal sides and six edges. Hexa comes from Greek word “Hex” meaning “six” in English and “gonia” meaning angles. Naturally, the perimeter of the hexagon will be 6 multiplied by one side of the hexagon. Each internal angle of the hexagon is $120^{\circ}$.

Formula of Perimeter of Hexagon:

$\large P=6\times a$

### Solved Examples

Question: Find the perimeter of the hexagon with one side 12 cm ?

Solution:

Given,
a = 6 cm

Formula of hexagon perimeter,

P = 6 $\times$ a

P = 6 $\times$ 12

P = 72 cm
