Question

3. Find the lateral surface area of the figure

below.


No links please I really need an answer

Answer 1

284
`ft^(2)`

Explanation:

Area of triangle = bh/2 = 4(8)/2 = 16

Area of both triangles = 32

Area of left face = bh = 8(12) = 96

Area of right face = bh = 9(12) = 108

Area of bottom = bh = 4(12) = 48

Total lateral area = 32 + 96 + 108 + 48 = 284
