Answer:
1. Find the area of the rectangle in square yards. In this case, the area is 9 yards * 3 yards = 27 square yards.
2. Convert square yards to square feet. There are 9 square feet in 1 square yard. So, the area of the rectangle in square feet is 27 square yards * 9 square feet/square yard = 243 square feet.
Therefore, the area of the rectangle floor in square feet is 243 square feet.
