A regular pentagon has an apothem of 3.2 m and an area of 37.2 square meters. What is the length of one side of the pentagon?

1 answer:

4 0

Area = # sides * side length * apothem / 2
side length = (2 * area) / # sides * apothem
side length = 2 * 37.2 / 5 * 3.2
side length = 74.4 / 16
side length = 4.65 meters
