Question 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.
We have a floor with dimensions 4 m width and 5 m length.
A square carpet of side 3 m.
Area of the floor = length × breath
Area of the floor = 5 × 4 = 20 m
2
Area of the square carpet = 3 × 3 = 9 m
2
Now, we will subtract the square carpet area from the floor’s area to get the area of the floor that is not carpeted.
Hence, the area of the floor that is not carpeted = 20 – 9 = 11 m
2
Thus, the area of the floor that is not carpeted is 11 m
