Answer:

A) 264 ft^2, 4 gallons

Step-by-step explanation:

Area of rectangle = 12 ft x 18 ft = 216 ft^2

Area of triangle = 1/2 (28- 18)(12) = 1/2(10)(12) = 60 ft^2

Area of window: 3 ft x 4 ft = 12 ft^2

Areas will be painting = (216 + 60) - 12 = 264 ft^2

1 gallon of paint will cover 70 ft^2 so 264 ft^2 / 70 ft^2 = 3.77 gallons

So Mr. Williams will need 4 gallons of paint to cover 264 square feet of his barn
