Draw a broken line ABCD, if the length of the AB link is 6 cm, the length of the BC link is 2 times less, and the length of the CD link is 2 cm longer than the length of the BC link. Find the length of the polyline.

1) To find the length of the broken line ABCD, you need to find the length of each link separately.
2) The length of the AB link is already known – 6 cm.
3) Since the length of the BC link is 2 times less than the length of the AB link, the length of the AB link must be divided by 2. 6/2 = 3cm. The length of the BC link is 3cm.
4) Since the CD link is 2 cm longer than BC, add 2 cm to the BC link.
3 + 2 = 5 cm. The length of the CD link is 5 cm.
5) Find the length of the entire polyline. AB + BC + CD = 6 + 3 + 5 = 14cm.
Therefore, our answer is: 14 cm.
