Question

A painter is painting a rectangular wall that measures 22.8 ft by 17.3 ft. Each gallon can of paint covers 100 square feet. What are the fewest gallons needed to paint the wall?

____gallons

Answer 1

1.548 gallons

Explanation:

Length of the rectangular wall = 25.1 ft.

Width of the rectangular wall = 18.5 ft.

Area of the rectangular wall = length * width = 25.1 * 18.5

= 464.35 square feet

300 square feet wall can be painted using 1 gallon of paint.

=> 1 square feet wall can be painted using gallon of paint.

=> 464.35 square feet wall can be painted using gallon of paint.

= 1.548 gallons of paint

Answer 2

4 gallons

Explanation:

The first thing you want to do is times 22.8 * 17.3 = 394.44. Then what you want to do is see how much 100 square gallons can cover the area : 4. If we make it 3 it is going under if it is 4 it can cover the whole thing, and if we make it 5 we have a little much.
