Question

Amelia wants to paint 3 walls in her family room. Two walls are 26 feet long by 9 feet wide. The other wall is 18 feet long by 9 feet wide.

A. What is the total area of the walls that Amelia wants to paint?
B. Each gallon of paint covers about 250 square feet. How many gallons of paint should Amelia buy to paint the walls?

Answer 1

x = 2.52 gallons. It is best that she buy 3 gallons of paint.

Explanation:

Wall 1 & 2 : 26 ft by 9 ft

Wall 3 : 18 ft by 9 ft

Area 1 : 26 ft x 9 ft = 234 ft²

Area 2 : 26 ft x 9 ft = 234 ft²

Area 3 : 18 ft x 9 ft = 162 ft²

Total Area : 234 ft² + 234 ft² + 162 ft² = 630 ft²

1 Gallon = 250 ft²

630 ft² ÷ 250 ft² per gallon = 2.52 gallons

Amelia will need 2.52 gallons of paint to cover the wall space of 630 ft^2
