Answer:
162 m²
Step-by-step explanation:
To find the area of this composite solid, we need to find the area of each surface and sum them up.
Formula for finding area is length x width.
Area of each surface:
3 * 2 = 6
9 * 2 = 18
5 * 2 = 10
2 * 2 = 4
8 * 2 = 16
(11-2) * 3 = 27
Considering the fact that each surface appeared twice in the figure, the area of the surface will be calculated as:
(6 + 18 + 10 + 4 + 16 + 27) * 2
= 81 * 2
= 162 m²
