The area of the living room = 12 * 15 = 180 square feet

The area of the rug is 5/9 of that, so

the area of the rug = 5/9 * 180 = 100 square feet

The rug is square, so

the area of the rug = (side length)^2

Since we just found out what the area of the rug is, put that value in for the area and solve for the side length.

100 square feet = (side length)^2

Take the + square root of both sides.

√100 = side length

10 feet = side length
