The perimeter of triangle is 480m.the second side is three times the first and the third side 60m more than the second.find the dimension of this triangle.
***
let x=first side
3x=second side
3x+60=third side
x+3x+3x+60=480
7x=420
x=60
3x=180
3xx+60=240
..
first side=60m
second side=180m
third side=240m
