Question

The length of a rectangular hall is $\mathit{4}\mathit{}meters$ less than $3times$ the breadth of the hall. What is the length, if the breadth is$bmeters?$

Answer 1

Given that breadth of rectangular hall$=bmeters$

According to the question, length of a rectangular hall is $\mathit{4}\mathit{}meters$ less than $3times$ the breadth of the hall.

Therefore, length$=(3\times b-4)meters$

Hence, the lenth of the rectangular hall is $(3b-4)meters$
