take the sides as 12x,17x and 25x
than plus all and equate with parameter
you will get x=10
now get measure of sides and find the area

ratio of sides =12:17:25perimeter =540
let 12=12x
17= 17x
25=25x
sides of all side =perimeter
12x+17x+25x =540
54x=540
x=10
semi semiperimter =540/54=27
now applying heron,s formula
answer =9000m^
hope it helps
thanks brother
