Answer:

A = 3 ft, B = 7 ft, C = 4 ft, D = 5 ft, Surface Area = 96 ft^2

Step-by-step explanation:

<u>Step 1:  Determine the sides</u>

A → 3 ft

B → 7 ft

C → 4 ft

D → 5 ft

<u>Step 2:  Determine the surface area</u>

Area of the sides

A= 4\ ft * 7\ ft = 28\ ft^2

A= 5\ ft * 7\ ft = 35\ ft^2

A= 3\ ft * 7\ ft = 21\ ft^2

Area of the top and bottom triangles

A= \frac{h\ *\ b}{2} = \frac{3\ ft\ *\ 4\ ft}{2} = \frac{12\ ft^2}{2} = 6\ ft^2 = 2(6\ ft^2) = 12\ ft^2

Total Area

28\ ft^2 + 35\ ft^2 + 21\ ft^2 + 12\ ft^2

96\ ft^2

Answer:  A = 3 ft, B = 7 ft, C = 4 ft, D = 5 ft, Surface Area = 96 ft^2
