Answer:

The surface area for the three rectangles is 48, 42, and 40 cm^2.

The surface area for the two triangles is 20 and 20, but for triangles, when you are finding the area of a triangle, you have to divide by 2.

4x5=20

20รท2=10

Now, do the same for the other triangle.

10+10=20.

Now, add all the surface areas together.

48+42+40+20=150

Surface area= 150 cm^2

:)
