Question

The length of a rectangular hall is 3 meters less than 4 times the breadth of the hall. What is the length if the breadth is b meters?

Answer 1

Answer:

If the breadth of the rectangular hall is b meters, and its length is 3 meters less than 4 times the breadth, then the length of the hall is 4b-3

Step-by-step explanation:

Given the breadth of hall = b meters

Given that length = 3 meters less than 4 times the breadth

So Length l= 4b-3

Answer 2

Answer:

The length of a rectangle is $(4b-3)$ meters.

Step-by-step explanation:

Given : The length of a rectangular hall is $3$ meters less than $4$ times the breadth of the hall.

           Breadth = $b$ meters

To find : What is the length if the breadth is b meters?

Solution :

• It is given that the length of a rectangular hall is $3$ meters less than $4$ times the breadth of the hall.

        Breadth = $b$ meters

• Now, according to given condition, the equation for length of a rectangle becomes,

    Length of a rectangle = $(4b-3)$ meters

• ∴ The length of a rectangle is $(4b-3)$ meters.
