Question

The length of a rectangular hall is 4 metres less than 3 times the breadth of the hall.What is the length, if the breathing b metres ​

Answer 1

In context to questions asked

We have to determine the value of the length of rectangular hall

As per questions

We have

Breadth of rectangular hall is b meters

The length of a rectangular hall is 4 metres less than 3 times the breadth of the hall

So 3 times the breadth of hall will be

$3 \times b \: = 3b$

4 m less than 3 times the breadth of hall will be

$3b - 4$

So from above

We will get,

$length = 3b - 4 \: m$

Hence value of length of rectangular hall will be (3b - 4) m

Answer 2

Answer:

The length of the hall is (3b-4) metres.

Step-by-step explanation:

A rectangle has 4 sides, the longer sides are called the length and the shorter ones are called the breadth. The length and breadth are perpendicular to each other.

Here it is given that the breadth of the rectangular hall is b metres.

It is also said that the length of the hall is 4 metres less than 3 times the breadth of the hall, so the length is equal to (3b-4) metres.
