Let each side be x
one equal side = 3x + 2
(3x + 2) x 2 + x = 67
7x + 4 = 67
7x = 67 - 4 = 63
x = 63 / 7 = 9

equal side = 3 x 9 + 2 = 27 + 2 = 29 
third side = 9

Let the third side be 'x'

Now, the two other sides are 3x + 2

Perimeter = 67
x + 3x +2 + 3x + 2 = 67
7x = 63
x = 9 cm


So, one side = x = 9 cm
Other two sides = 3x + 2 = 18 + 2 = 20 cm
