Hi there! The answer is 61.5 square feet.
The area of a rectangle can be found using the formula:
A = L × W = length × width
The area of the floor is
12 × 10 = 120 square feet.
The area of the rug is
6.5 × 9 = 58.5 square feet.
The area of the floor that is not covered by rug is
120 square feet - 58.5 square feet =
61.5 square feet.
The answer is 61.5 square feet.
~ Hope this helps you!
