 ## How to Find the Perimeter of Polygons

### Way to Determine the Perimeter of a Polygon

A perimeter is described as the sum of the length of each side. For instance, in a quadrilateral whose sides are $$9, \ 7, \ 5$$ and $$11$$, the perimeter is provided by: Perimeter $$= \ 9 \ + \ 7 \ + \ 5 \ + \ 11 \ = \ 32$$

With a Regular polygon, whose sides are all of the equal length, its perimeter is described as,

Perimeter $$= \ n \times s$$ Units

• where $$n \ = \ number \ of \ sides \ of \ a \ polygon$$,
• and $$s \ =$$ length of a side
