# In the polyline KLMN all links have a length of 23cm find the length of this polyline.

Finding the length of a polyline klmn, if the given polyline is closed
the length of a broken line is the sum of the lengths of its links;
segments kl, lm, mn, nk are links;
kl = lm = mn = nk = 23 centimeters.
Then the length of the broken line klmn will be equal to:

4 * 23 = 92 centimeters.

Finding the length of a polyline klmn if the given polyline is not closed
the length of a broken line is the sum of the lengths of its links;
