Amelia wants to paint three walls and a family room to was a 26 long by 9 feet wide the other wall is 18 feet long by 9 feet wide each gallon of paint covers that 250 ft.² how many gallons of paint should amelia buy to paint the wall

Given:
2 walls = 26 ft long by 9 ft wide
3rd wall = 18 ft long by 9 ft wide

Area = 26 ft * 9 ft = 234 ft²
2 walls ⇒ 234 ft² * 2 = 468 ft²

3rd wall area = 18 ft * 9 ft = 162 ft²

Total area = 468 ft² + 162 ft² = 630 ft²

630 ft² ÷ 250ft² per gallon = 2.52 gallons

Amelia should be 2.52 or 3 gallons to paint the 3 walls.
