20. A floor is 6 m long and 5 m 3 po
wide. A square carpet of sides
3 m is laid on the floor. Find the
area of the floor that is not
carpeted.
*​

Answer 1

Step-by-step explanation:

Length of the floor is 5m

The breadth of the floor is 4m

So, ( applying ar. l×b )

ar. of floor =4m×5m=20²m

. Side of the carpet is 3m

So, (applying ar. of sq. =side×side(s))

area of carpet=3m×3m=9²m

.

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 ) =20²m

−9²m

=11²m

Answer : 11²m
