A floor is 5 m long and 4 m wide. A square carpet of side 3 m is laid on the floor. Find the area of the floor that is not carpeted.
The figure is given below:
We know that,
Area of rectangle = Length × Breadth
It is given in the question that,
Length of rectangle = 5 m
Breadth of rectangle = 4 m
Therefore,
Area of floor = Length × Breadth
= 5 × 4
= 20 m2
Also,
Area covered by the square carpet = (Side)2
= (3 m)2
= 9 m2
Therefore,
Area of the floor that is not carpeted = Area of Rectangle - Area of square
= 20 m2 – 9m2
= 11 m2
