Trying to find the right answer to this..

Let the breadth of the rectangular hall be ‘x’ m. So, length be (x + 3) m According to question, Area = 180 i.e., Length x breadth = 108 ⇒ x(x + 3) = 108 ⇒ x 2 + 3x = 108 ⇒ x 2 + 3x – 108 = 0 Therefore, the required representation in the form of quadratic equation be x 2 + 3x – 108 = 0.

58. Represent the following situation in the form of a quadratic equation:
The length of a rectangular hall is 3 m more than its breadth. If the area of the hall is 108 m².

Let the breadth of the rectangular hall be ‘x’ m.
So, length be (x + 3) m
According to question,
Area = 180
i.e., Length x breadth = 108
⇒ x(x + 3) = 108
⇒ x² + 3x = 108
⇒ x² + 3x – 108 = 0
Therefore, the required representation in the form of quadratic equation be x² + 3x – 108 = 0.
