Area of the barn to be painted = Area of the (rectangular base + Triangular top) - Area of the window
Area of the rectangular base = 12 × 18
= 216 ft²
Area of the triangular top =
=
= 60 square feet
Area of the window = 3 ft × 4 ft
= 12 ft²
Total area to be painted = 216 + 60 - 12
= 264 ft²
∵ 70 square feet of the barn is covered by the amount of paint = 1 gallon
∴ 1 square feet will be covered by the amount = gallons
∴ 264 square feet will be painted by =
= 3.77 gallons
≈ 4 gallons
Therefore, Option (A). 264 ft²; 4 gallons will be the answer.
