Question

Elaine pained a fence. She has already determined that she needs 1 gallon of paint total for each 10 feet of fencing to finish the entire job. The fencing will enclose a rectangular yard that is 3 yards long and 2 yards wide. How much paint does Elaine need?

Answer 1

Hi there! The answer is 3 gallons of paint

First we need to find the circumference of the yard, which is a rectangle. We can find the circumference of a rectangle by using the following formula.

circumference = 2 × length + 2 × width
circumference = 2 × 3 + 2 × 2
circumference = 10

Therefore, the circumference of the rectangle is 10 yards.

1 yard = 3 feet
10 yards = 30 feet.

Elaine needs 1 gallon of paint for each 10 feet of fencing, thus she needs a total of 3 gallons of paint to paint the fence.
