Answer:
912m
Step-by-step explanation:
There are two triangles.
The height of the triangles are 16m and the base is 12m.
Multiply 12(16)/2 to get the area of the triangle.
The area of the triangle is 96m.
Multiply 96 by 2 to get 192.
There are three rectangles.
Height is 20m and the base is 12m
20(12) is 240. Then, multiply by three.
240(3) is 720.
Add 192 and 720 to get 912m.
Hope this helps! Comment if I did something wrong.
