Question

a room is 14m long and 12 m wide . a square carpet whose side 10 m is to be laid on its floor . find the area of the floor which is not carpeted....

Answer 1

Answer:

Given :

Length of the floor is 5m

The breadth of the floor is 4m

So, ( applying ar. l×b )

ar. of floor =4m×5m=20m²

. Side of the carpet is 3m

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

area of carpet=3m×3m=9m² .

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 ) =20m² − 9m²

= 11m²

.

Hence, answer Is 11 m².
