let the shortest side be x
longest side 3x
shortest side=x
third side =3x-2
3x+x+3x-2=61
7x=63
x=9cm
longest side is 21 cm
third side is 19cm
shortest side is 9cm
longest side 3x
shortest side=x
third side =3x-2
3x+x+3x-2=61
7x=63
x=9cm
longest side is 21 cm
third side is 19cm
shortest side is 9cm

let the shortest side be x.
so,longest side will be 3x.
third side will 3x-2.
ATQ,
perimeter of triangle= sum of all sides
61=x +3x+3x-2
61+2=7x
63=7x
x=63/7
x=9
so the shortest side will be 7cm.
so,longest side will be 3x.
third side will 3x-2.
