  • Question
  • The length of a rectangular plot is 20 metres more than its breadth. If the cost of fencing the plot @ 26.50 per metre is Rs. 5300, what is the length of the plot in metres?


  • Options
  • A. 40
  • B. 120
  • C. 50
  • D. None of these

  • Correct Answer
  • None of these 

    Explanation

    Let breadth = x metres.

    Then, length = (x + 20) metres.

    Perimeter = 5300 m = 200 m. 26.50

    2[(x + 20) + x] = 200

    2x + 20 = 100

    2x = 80

    x = 40.

    Hence, length = x + 20 = 60 m.
