1. Find the side of the triangle AB, if it is 2 times less than BC:

AB = BC / 2 = 6/2 = 3 (cm).

2. Find the AC if it is 2 cm larger than the BC:

AC = BC + 2 = 6 + 2 = 8 (cm).

3. Find the perimeter of the triangle ABC:

P = AB + BC + AC = 3 + 6 + 8 = 17 (cm).

Answer: The perimeter of triangle ABC is 17 cm.
