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 |
