Question

A room is 4.5 m long and 3.2 m wide. A carpet, 4 m by 3 m, is laid on the floor. Find the area of the floor that has not been covered..

Answer 1

To find the area of the floor that has not been covered by the carpet, subtract the area covered by the carpet from the total area of the floor.

Step-by-step explanation:

To find the area of the floor that has not been covered by the carpet, we need to find the area of the entire floor and subtract the area covered by the carpet.

The area of a rectangle can be calculated by multiplying its length by its width. In this case, the room is 4.5 m long and 3.2 m wide, so the area of the entire floor is 4.5 m * 3.2 m = 14.4 square meters.

The area covered by the carpet is 4 m * 3 m = 12 square meters.

To find the area of the floor that has not been covered, we subtract the area covered by the carpet from the total area of the floor: 14.4 square meters - 12 square meters = 2.4 square meters. Therefore, the area of the floor that has not been covered is 2.4 square meters.
