    Answer : Option C

    Explanation :

    Let the length of the rectangle be 5x, and breadth be 3x,
    Perimeter of a rectangle = 2(l +b) = 480
                                             2(5x + 3x) = 480
                                             2 x 8x = 480
                                             16x = 480
                                             x = 480/16 = 30

    ∴ Length = 5 x 30 = 150 m
                      Breadth = 3 x 30 = 90 m

    And, Area of rectangle = L x B
                                         = 150 x 90 = 13500 m2
