Answer:
ratio of the sides=12:17:25
let the sides be 12x ,17x and 25x
perimeter =540cm
540=12x+17x+25x
540=54x
x=10
sides of triangle are
a= 120cm,
b=170cm and c=250cm
semi perimeter =s=a+b+c/2=
120+170+250/2=540/2=270cm
area of triangle =root(s(s-a)(s-b)(s-c))
=root(270(270-120)(270-170)(270-250))
=root(270×150×100×20)
=root81000000
=9000cm²
