The perimeter of a church window is 60 inches. if the window is in the shape of a regular pentagon, what is the length of each side of the window?
a. 10 inches
b. 8 inches
c. 12 inches
d. 6 inches

The length of each side of pentagonal church window with the perimeter of 60 inches is C. 12 inches. The perimeter (P) of a pentagon is the sum of its side lengths (s). Since pentagon has 5 sides, the perimeter of the pentagon is: P = 5s. If we know that the perimeter is 60 inches, the side length will be: 60 in = 5s. s = 60 in / 5. s = 12 in. The length of the side of the window is 12 inches.

11/2.2 = 5 inches for the length 8.5/2.2= 3.86 inches for the width
