108 ft2

B.

C.
36 ft2

D.
27 ft2

Answer 2

please someone help

Answer 3

The easy way to do this:
We know that all triangular faces are congruent. And we know the total surface area is 144 sq ft.
So, we can Subtract 36 from 144. This will equal the total surface area of the triangular faces. 144-36=108
Divide 108 by 4 since there are 4 faces. This will equal the surface area of one triangular face.
