Question

A 4 metre wide rectangle is cut off from a square. the area of the remaining rectangle is 60 m square what is the length of a side of the square
​

Answer 1

Step-by-step explanation:

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

2

.

Hence, answer Is 11m
