What length of carpet, 63 cm wide, is needed to cover the floor of a room measuring 14 meters by 9 meters?

Explanation

To find the required length of carpet, first calculate the area of the room: 14 m × 9 m = 126 m². Since the carpet is 63 cm (0.63 m) wide, the length needed is area divided by width: 126 m² ÷ 0.63 m = 200 meters.
