Question

Maria is decorating her school's cafeteria for the end- of- year dance. The dimensions of the room are labelled below. What is the smallest length of streamer that will go around the entire perimeter of the room? Round your answer to the nearest foot.

Answer 1

59 feets

Explanation:

The length of bottom base = (8 + 2 + 2) = 12

Circumference of semicircle : 2πr/2 ; r = 4/2 = 2

Circumference of semicircle = π * 2 = 6.28

Length of streamer that will go around the entire perimeter :

From the figure attached :

Circumference of semicircle = 6.28

6.28 + 6 + 2(down) + 2(right) + 8(down) + 2(left) + 2(up) + 2(left) + 2(down) + 8(left) + 10

6.28 + 6 + 2 + 2 + 8 + 2 + 2 + 2 + 2 + 8 + 10 = 50.28 feets = 50 ft (nearest whole number)
