How do you think this problem should be solved?

Remember: there are two walls of one size and two walls of another size.

No. Picture each wall as a rectangle. Find the area of each wall.

What about the height of the walls?

Answered by Ms. Sue
Let's start over.

Two walls are 12 feet by 7 feet.
A = 2(12 * 7) = 168 square feet

Two walls are 15 feet by 7 feet.
A = 2 (15 * 7) = 210 square feet

210 + 168 = 378 square feet of walls

It sounds like just one gallon of paint will cover the four walls.
