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

Answer:Length of the floor =5m

and its breadth =4m∴ Area of the floor =1ength× breadth =5m×4m=20sqm

Side of the carpet =3m

∴ Area of the square carpet

= side × side =3m×3m=9sqm

∴ Area of the floor which is not carpeted

=20 sq m−9 sq m=11 sq m .

Step-by-step explanation:

Answer 2

Answer:

$Given :Length of the floor is 5mThe breadth of the floor is 4mSo, ( applying ar. l×b )ar. of floor =4m×5m=20m 2 . Side of the carpet is 3mSo, (applying ar. of sq. =side×side(s))area of carpet=3m×3m=9m 2 To find the area of the floor that is not carpeted or (uncarpeted) we will (−) minus the ar. of the floor from ar. of carpet area which is not carpeted or( uncarpeted ) =20m 2 −9m 2=11m 2Hence, answer Is 11m 2$

Step-by-step explanation:

Answer:Length of the floor =5m

and its breadth =4m∴ Area of the floor =1ength× breadth =5m×4m=20sqm

Side of the carpet =3m

∴ Area of the square carpet

= side × side =3m×3m=9sqm

∴ Area of the floor which is not carpeted

=20 sq m−9 sq m=11 sq m .
