Are you asking: "how long does a flatworm live?"
If so, this is not an answerable question--there are too many types of flatworms to make a generalization.
I personally know of one type of flatworm which can re-generate--cut off any part of it's body, and that part will re-generate. As long as the head remains attached, the re-generation can take place.
I did a science project using freshwater planarians, where I explored this phenomenon.
The longest flatworm ever found was about 20 meters long.
170 years
