# How to Find the Perimeter of Polygons

Polygons are some-sided figures, with line segments as their sides. Learn how to find the perimeter of a polygon in this article.

## Step by step guide to find the perimeter of Polygons

• Perimeter of a square $$=4×side=4s$$
• Perimeter of a rectangle $$=2(width \ + \ length)$$
• Perimeter of trapezoid $$= a+b+c+d$$
• Perimeter of a regular hexagon $$=6a$$
• Perimeter of a parallelogram $$=2(l+w)$$

### Polygons – Example 1:

Find the perimeter of following regular hexagon.

Solution:

The perimeter of Pentagon $$=6a$$
Perimeter of Pentagon $$=6a=6×5=30$$ m

### Polygons – Example 2:

Find the perimeter of following regular hexagon.

Solution:

Perimeter of Pentagon $$=6a$$
Perimeter of Pentagon $$=6a=6×3=18$$ m
