the perimeter of a triangle is 110 cm one side is twice the second side the third side is 30 cm more than the second side find the length of both side find the length of each side
..
let the second side be x
other side = 2x
third side = x+30
..
x+2x+x+30 =110
4x+30=110
4x=80
x=20 second side
other side = 2x=40
third side = x+30 = 20+30=50
..
Check
20+40+50=110
