    Answer : Option E

    Explanation :

    Let breadth = x metres.

     

    Then, length = (x + 20) metres.

     

    Perimeter =\([\frac {5300 } { 26.50 }]\) m=200m

     

     2[(x + 20) + x] = 200

     

     2x + 20 = 100

     

     2x = 80

     

     x = 40.

     

    Hence, length = x + 20 = 60 m.
