There is a hidden trap in this question. Remember that the dimensions of this room are square feet, not feet (because 5 feet × 4 feet = 20 square feet). To avoid this trap, you should convert the dimensions to inches first, then multiply. 5 feet × 4 feet = 60 inches × 48 inches
The dimensions of the closet in inches are 60 inches by 48 inches, or 60 × 48 = 2,880 square inches. Each tile is 1 square inch, so it will take 2,880 tiles to cover the floor.
Answer: E
