Find the perimeter of this figure. Please show work.

Elena-2011 [213]

Answer:

40.56 ft

Step-by-step explanation:

The perimeter is the sum of the lengths of the "sides" of this figure. Starting from the left side and working clockwise, the sum is ...

P = left side (8 ft) + top side (10 ft) + semicircle (1/2×8 ft×π) + bottom side (10 ft)

= 28 ft + 4π ft

= (28 +12.56) ft

P = 40.56 ft
