The floor of a room is 5 m long and 4 m wide. A square carpet whose sides are 3 m in length is laid on the floor. Find the area that is not carpeted.

Correct Answer

Step 1: Area of the floor = length × width = 5×45 \times 4 = 20 sq m

Step 2: Area of the square carpet = side × side = 3×33 \times 3 = 9 sq m

Step 3: Area not carpeted = Area of floor - Area of carpet = 20 - 9 = 11 sq m
