If each side of a regular pentagon equals 4 feet what is the perimeter

In a regular polygon, all of the sides have the same length.

Pentagons have five sides. If one of the sides in a regular pentagon is 4 feet, then the rest will also be four feet. 5 sides that are all 4 feet long totals up to a 20-foot perimeter.

A regular polygon has all sides equal. There are 5 sides all equaling 4 ft, so 4⋅5 = a 20 ft perimeter.
