Question

The length of a rectangular hall is 7 meters less than 2 times the breadth of the hall. What is the length, if the breadth is b meters?

Answer 1

Step-by-step explanation:

ANSWER:-

GIVEN:-

• The length of the Rectangle halls is 7 metres less than twice the breadth.
• So, we need to assume here the breadth as b.

Concept:-

Perimeter and Area

Let's Do!

So, let us assume the breadth as b.

So, according to the statement,

$\rm{Length = 2b - 7}$

So, this was the required answer.

More Formulas:-

• Perimeter of Rectangle = 2 ( Length + Breadth)
• Area of Rectangle = Length × Breadth

• Perimeter of Square = 4 × Side
• Area of square = (Side)²

Answer 2

Answer:

2b-7 m

Step-by-step explanation:

Breadth of the hall= b m(meters)

Length of the hall

= 2 × (breadth of the hall) - 7

= 2 × b - 7

= 2b-7

Thus, the length of  the hall is 2b-7 m(meters)
