12:17:25
perimeter = 540
let a=12x
b=17x
c=25x
perimeter=a+b+c
540=12x+17x+25x
540=54x
x=540/54 =10
x=10
therefore, a=12*10=120
b= 17*10=170
c= 25*10=250
SEMI-PERIMETER = 540/2=270
note: area is founded in upper image
I hope that this will be helpful to you.....

12x+17x+15x=540
44x=540
x=540 /44
area =√s×s-a*s-b*s-c
s= 540/2
=270
44x=540
x=540 /44
area =√s×s-a*s-b*s-c
