a regular pentagon has an apothem of 3.2 and an area of 37.2 cm. What is the length of one side of the pentagon?

Answers

Answered by Reiny
area of one triangle = 37.2/5 = 7.44 cm

area = (1/2)base x height
7.44 = (1/2)(base)(3.2)
base = 2(7.44)/3.2)
= ...
Answered by Steve
Or, using the formula area = 1/2 * apothem * perimeter,

that will give you the perimeter. 1/5 of that will be the side length.
