3. A painter paints 240 sq. feet of a wall. If this is 48% of the total wall surface, what is thearea of the wall in sq. feet?

Answer»

Let the total wall surface area = x sq. ft

area of wall in sq. ft = 48% of x= 48/100 × x= 48x/100

area painted = 240 sq. ft48x/100 = 240x = 240 × 100 / 48= 500 sq. ft
