Given:
Length of the side of the pentagon = b cm
To find:
Perimeter of a regular pentagon.
Solution:
A regular pentagon is a polygon that have five equal sides in it. While the perimeter of a polygon is the sum of the length of all the boundaries of the polygon.
Here since the length of one side = b cm
The perimeter of all the sides will be P = b + b +b+ b+ b = 5b cm
The perimeter of the pentagon is 5b cm.
