The square feet need to be painted will be equal to the product of  height and width of the wall i.e surface area of the wall

Let the width of the wall be 10 feet

Surface area of the wall = H * W

Where H is the height of the wall in feet

W is the width of the wall in feet

Substituting the given values in above equation, we get -
