Amelia wants to paint three 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 each gallon of paint covers about 250 square feet. how many gallons of paint should amelia buy to paint the walls

Given:
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
