Answer:
756 m^2
Explanation:
Area of 2 Triangles
A = (b×h) ÷ 2
Substitute:
(12 × 9) ÷ 2
108 ÷ 2 = 54
There are 2 triangles so:
54 × 2 = 108 m^2
Area of 3 Rectangles
A = L × W
Rectangle on the left:
Substitute:
12 × 18 = 216 m^2
Rectangle in front:
9 × 18 = 162 m^2
Rectangle behind:
15 × 18 = 270 m^2
Add Them All Together
- We have worked out all the areas of the shapes, now we need to add them all together to get the total surface area.
108 + 216 + 162 + 270 = 756
Total surface area = 756 m^2
