Length of floor is 5m
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 floor from ar. of carpet
area which is not carpeted or( uncarpeted ) =20m2-9m2
=11m2.
Hence,the ans. Is 11m sq.
