    Answer:

    Let the sides be 12x, 17x, 25x.

    Then, perimeter = 12x+17x+25x=540 (given)

    = 54x = 540

    =x = 540/54

    = x= 10.

    Hence 12x = 12*10= 120

    17x= 17*10 = 170

    25x= 25*10 = 250.

    Hence S= 120+170+250/2 = 270

    270-120 = 150

    270-170= 100

    270-250 = 20

    Area of triangle = 8100000

    = 900
