the area of the floor that is not carpeted.
​

Answer 1

area is 7x5 is 35

and it is 4m

therefore 31 m is not carpeted

Step-by-step explanation:

Answer 2

Given :
Length of the floor is 5m
The breadth of the floor is 4m
So, ( applying ar. l×b )
ar. of floor =4m×5m=20m
2
. Side of the carpet is 3m
So, (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

.
Hence, answer Is 11m
