Answer:
We must calculate the length of the "slope"
Hypotenuse^2 = 11^2 + 4^2
Hypotenuse^2 = 121 + 16
Hypotenuse^2 = 137
Hypotenuse = 11.7
Area of "slope" surface = 11.7 * 6 = 70.2 sq feet
Area of Base = 6 *4 = 24 sq feet
Area of rear side = 6 * 11 = 66 sq feet
Area of both sides = 44 sq feet
Total area = 70.2 + 24 + 66 + 44 = I get 204.2 which is NOT any of the choices.

Geez, I recalculated everything and still got the same answer. Any idea where I went wrong?
