A 10 m long and 8 m wide rectangular floor is to be covered with a square carpet with 4 m sides. How many square meters of the floor are uncovered?
Thoughts? Step-by-step reasoning:
The area of the floor is 10 m x 8 m = 80 square meters. The area of the carpet is 4 m x 4 m = 16 square meters. Therefore, the area of the floor not covered by the carpet is 80 square meters - 16 square meters = 64 square meters,.
Thus, the answer is 64.
