Question

floor is 5 M long and 4 metre wide a square carpet of side 3 M is laid on the floor find the area of the floor that is not carpeted

Answer 1

area of floor=20m sq

20-9=11m sq area is not carpeted

Answer 2

Answer :

The figure is attached

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
