Given

Length of the room =12.5 m

Breadth of the room =8 m

Area of the room = (length \times breadth)

=(12.5×8) m

2

=100 m

2

Square carpet side =8 m

Area of the square carpet =(side)

2

=(8)

2

=8×8

=64 m

2

Area of the floor which is not carpeted = (Area of the room)-(Area of the carpet)

=(100−64) m

2

=36 m

2

Hence, area of the room which is not carpeted is 36 m
