The length of the Line segment LM is LM = 26 units.
We are told that;
L is the midpoint of JM. Thus;
JL = LM
Now, we are told that K is the midpoint of JL. Thus;
JK = KL
Now, by virtue of the fact that JL = LM and that JK = KL, we can say that;
LM = 2(JK)
We are given that JK = 13. Thus;
LM = 2 * 13
LM = 26
Thus, we conclude that the length of the Line segment LM is LM = 26 units.
