Answer»

Solution:

Given: AREA of the rectangular hall = 744 m² and 

LENTH of the rectangular hall is 7M more than its breadth.

Let us TAKE 'l' as the length and 'b' as the breadth of the hall.

So, we have l = 7 + b 

Area of the rectangular hall = 744 m²

Length × Breadth = 744 

l × b = 744

Substituting 'l' here we get 

(7+b)b = 744

b² + 7b - 744 = 0

(b + 31)(b -24) = 0

So, b = 24m

Substituting the value of 'b' in l = 7 + b 

We have l = 7 + 24

So, l = 31m

The CORRECT option is 4). 31m
