Question

The total cost of flooring a room at ₹ 8.50 per square metre is ₹ 510.If the length of the room is 8 metres, find its breadth.

Answer 1

Let the area of floor be x
But, total cost of flooring = 510
A. T. Q,
Area *cost of flooring per square. metre =510
x*8.5=510
x*85/10=510
x=510*10/85
x=60
Hence, area =60sq m
Length =8 m (Given)
Hence, area =60sq m
Length =8 m (Given)
Breadth=?
Area = L*B
60=8*b
60/8=b
7.5=b
b=7.5
Hence, breadth =7.5m
