Answer 2

length=8m

rate of flooring the room is ₹85 per metre square and the total cost is ₹5100

area of room × rate of flooring=
total cost of flooring.

area of room×85=5100

area of room=5100/85

area of room=60sq.m

we know that,

area of room=length × breadth

60=8×breadth

breadth=60/8

breadth=7.5m

Therefore,
the breadth of the room is 7.5m
