Option A. 264 ft² ; 4 gallons
Step-by-step explanation:
Given question is incomplete; find the complete question in the attachment.
From the picture attached,
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 = [tex]\frac{1}{2}(\text{Base}\times \text{Height})[/tex]
= [tex]\frac{1}{2}(12)(28-18)[/tex]
= 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 = [tex]\frac{1}{70}[/tex] gallons
∴ 264 square feet will be painted by = [tex]\frac{264}{70}[/tex]
= 3.77 gallons
≈ 4 gallons
Therefore, Option (A). 264 ft²; 4 gallons will be the answer.
