Question

what is the perimeter, in feet, of the polygon?
a. 105
b. 185
c. 192
d. 210

Explanation:

Step1: Identify all side - lengths

The side - lengths are 15 ft, 22 ft, 10 ft, 18 ft, 14 ft, 5 ft, 16 ft, 5 ft. Also, we need to find the missing horizontal and vertical side - lengths. The missing horizontal side on the left is 22 + 18+14+16 = 70 ft. The missing vertical side on the top is 15 + 10+5 = 30 ft.

Step2: Sum all side - lengths

Perimeter = 15+22 + 10+18+14+5+16+5+70+30
Perimeter = 192 ft

Answer:

C. 192
