Four quarts of a latex enamel paint will cover about 120 square feet of wall surface. Howw quarts are needs to cover 67 square feet of kitchen wall and 53 square feet of bathroom.
So...I assume that we want to know how much paint we need to cover the kitchen wall and the bathroom
We can solve this with a proportion
4 / 120 = x / ( 67 + 53) where x is the amount of paint we need
4 /120 = x / 120
So....it appears that x = exactly 4 quarts
