Answer 1

$\huge\red{A}\pink{N}\orange{S} \green{W}\blue{E}\gray{R} =$

The length is (3 b - 4) meters.

Step-by-step explanation:

We have given,

Breadth of the rectangle = b meters,

Since, length of a rectangular hall is 4 meters less than 3 times the breadth of the hall,

Length = 3 x Breadth + 4

Length = 3b + 4,

Hence, the length of the rectangle is (3 b - 4) meters.

Answer 2

Step-by-step explanation:

The length is (3 b - 4) meters.

Step-by-step explanation:

We have given,

Breadth of the rectangle = b meters,

Since, length of a rectangular hall is 4 meters less than 3 times the breadth of the hall,

Length = 3 x Breadth + 4

Length = 3b + 4,

Hence, the length of the rectangle is (3 b - 4) meters.
