Answer the following:
The length of a rectangular hall is 4 metres less than 3 times the breadth of the hall. What is the length, if the breadth is b metres?
According to the question,
We know that,
The breadth of the rectangular hall is b metres
Therefore,
Length of the rectangular hall = 3 × breadth – 4
l = (3 × b) – 4
l = 3b – 4
Hence,
The length will be 3b – 4
