A regular pentagon is a shape with 5 sides of equal length. Look at the relationship between the length of a side of a pentagon and the perimeter of the pentagon.
Pentagon Side Pentagon Perimeter
2 ft 10 ft
4 ft 20 ft
6 ft 30 ft
8 ft 40 ft

Which equation can be used to find p, the perimeter of the pentagon with sides of length s?
