Answer:
60yd²
Step-by-step explanation:
1. Find the Surface area of the Triangles
3x4x1/2=
12x1/2=
6
For both of the triangles =
6x2=12
So, the two triangle's surface area is 12 yd²
2. Find the surface area of the Base (rectangle)
4x4=16
So, the surface area of the base is 16yd²
3. Find the surface area of the back rectangle
3x4=12
So, the surface area of the back rectangle is 12yd²
4. Find the surface area of the top rectangle
4x5=20
So, the surface area of the top rectangle is 20yd²\
5. Add up all of the answers for Surface area.
12+16+12+20
12+16=28
28+12=40
40+20=60
So hence, your answer is 60yd²
