Answer:

Perimeter of base = 18 ft

Height = 7 ft

Base area = 12ft²

SA= 150 ft² *

Explanation:

Perimeter of base = 8+5+5=18 ft

Height = 7 ft

Base area = 1/2x8x3=12ft²

SA= (8x7)+(12+12)+2(5x7)=56+24+70=150 ft²

*There are several different way to figure out the surface area, so I’m not sure exactly how they want it displayed. 150 is the answer though. Plus, I think there was supposed to be an addition sign between the first two parentheses.
