Question

Please help total surface area

Answer 1

161ft

Explanation:

Area of a triangle is 1/2 (base x height)

2 triangles at:

1/2(5ft x5ft) = 12.5ft

1/2(5ft x 5ft) = 12.5ft

Then the area of the 3 rectangles

8 x 7 = 56ft

8 x 5 = 40ft

8 x 5 = 40ft

12.5ft + 12.5 + 56ft + 40ft + 40ft = 161 ft
