Stain required to stain the ramp = 2 quarts
Step-by-step explanation:
Area of the wheelchair ramp to be stained = Surface area of the ramp - Area of the rectangular base
Surface area of the ramp = 2(area of the triangular base) + (perimeter of the base)(height)
Area of the triangular base =
=
= in²
Perimeter of the triangular base =
= 25 + + 25 +
= 50 +
= 50 +
= ft
Surface area of the ramp = +
- 25×5
=
=
= 187.92 square feet
Since, 100 square feet area is covered by the stain = 1 quart
Therefore, 187.92 square feet will be covered by the stain =
= 1.8792
≈ 2 quarts
