Answer:

Stain required to stain the ramp = 2 quarts

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 =
(1)/(2)(\text{Base})(\text{Height of the triangle})

=
(1)/(2)(25)((25)/(12))

=
(625)/(24) in²

Perimeter of the triangular base =
25(1)/(12)+25+(25)/(12)

= 25 +
(1)/(12) + 25 +
(25)/(12)

= 50 +
(26)/(12)

= 50 +
2+(2)/(12)

=
52(1)/(6) ft

Surface area of the ramp =
(625)/(12) +
(52(2)/(12))* 5 - 25×5

=
(625)/(12)+(3130)/(12)-125

=
(3755)/(12)-125

= 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 =
(187.92)/(100)

= 1.8792

≈ 2 quarts
