Answer 1

C (108)

Im on the test right now ~edge~

Answer 2

Option (3)

Explanation:

The ramp shown in the figure is in the shape of a triangular prism.

Therefore, total surface area of this ramp = Area of the triangular sides + Area of the base + Area of the vertical side + Area of the slanting side

Area of the triangular sides =
`2[(1)/(2)(Base)* (h)]`

= bh

= 4×3

= 12 square feet

Area of the rectangular base = Length × Width

= 4 × 8

= 32 square feet

Area of the vertical side = Length × Width

= 3 × 8

= 24 square feet

Area of the slanting side = Length × width

= 8×5

= 40 square feet

Total surface area = 12 + 32 + 24 + 40

= 108 square feet

Option (3) will be the answer.
