# The AB side of the ABC triangle is half the size of the BC side, the AC side is 2cm larger

The AB side of the ABC triangle is half the size of the BC side, the AC side is 2cm larger than the BC side. Re-measure the ABC triangle if it is known that BC = 6 cm.

1) We find out how long the AB side has, if it is known that the BC side is 2 times longer, and the BC length is 6 cm.

6/2 = 3 cm.

2) Find out how long the AC side is, if it is known that the BC side is 2 cm shorter and the BC length is 6 cm.

6 + 2 = 8 cm.

3) Let’s find out what perimeter the triangle has, if we found all its sides and they made AB = 3 cm, AC = 8 cm and BC = 6 cm.

3 + 8 + 6 = 17 cm.

Answer: The perimeter of triangle ABC was 17 cm.
