26 by 9
Area = L*W
Area = 26 * 9
Area = 234 square feet but there are 2 such walls
Area = 234 * 2
Area = 468 square feet total for these walls.
18 by 9
Area = L*W
Area = 18 * 9
Area = 162 square feet
Total area = 468 + 162 = 630 square feet.
1 gallon covers 250 square feet
x gallon covers 630 square feet
1/x = 250/630
250 x = 1 * 630
x = 630 / 250
x = 2.52 gallons. It is best that she buy 3 gallons of paint.
