  • Question
  • The length of a rectangular hall is 5m more than its breadth. The area of the hall is 750 sq.m. The length of the hall is


  • Options
  • A. 20
  • B. 25
  • C. 30
  • D. 35

  • Correct Answer
  • 30 

    Explanation

    Let breadth = x m

     

    Then, length = (x+5)m

     

    Area of a rectangle = Length x Breadth

     

    x(x+5) = 750 

     

    x² + 5x - 750= 0

     

    (x+30)(x-25)= 0

     

    x = 25 or x = -30

     

    Hence, breadth x = 25m

     

    => Length = x + 5 = 25 + 5 = 30m.
