Answer:
The area of the pentagon is 249 square inches.
Step-by-step explanation:
Given, s = 12in; and a = 8.3, The formula to find the area of a pentagon with apothem is, Area of pentagon = 1/2 × perimeter × apothem. So, let us find the perimeter of the pentagon. Perimeter of the pentagon = 5 × side length.
perimeter = 5 x 12
= 60in.
Area = 1/2 × 60×8.3
= 249in².
