Points K L M are collinear. Find out the length of the cut KL if KM = 18cm LM = 11cm.

If points K L M lie on one straight line, then they form segments KL, LM and KM.

The length of the segments KM and LM is known.

KM = 18cm.

LM = 11cm.

So point L is located between points K and M.

Therefore, to find the length of KL, you need to subtract the length of the segment LM from the length of the segment KM.

KL = KM – LM

KL = 18 – 11 = 7

KL = 7 cm.
