Answer:
Since the cost of flooring the room @ rs 68 per square meter is rs 2040 ,
This implies that ,
=Area of the room × 68 = 2040
( We know that area of a rectangle is length × breadth)
= (7.5m × breadth) × 68 = 2040
=7.5m × breadth = 2040 ÷ 68
=7.5m × breadth = 30
=Breadth = 30÷7.5
= Breadth = 4m
Therefore,
Length of the room is 7.5m and breadth is 4m
