The length of the segment AB is 1.5. On ray AB, point K is taken, and on ray BA, point L so that AK = 0.7; BL = 2.1. Find the length of the line segment KL.

Since the Segment AK has a length of 0.7, it is located on the segment AB. Point K divides the segment AB into 2 parts AK and KB. AK = 0.7, according to the condition of the problem, the length AB = 1.5, then the length of the segment KB = 1.5-0.7 = 0.8.
The segment BL has a length of 2.1 cm, which is more than the length of the segment AB, i.e. point L lies behind point A.
The length of the segment KL can be found by subtracting the length of the segment KB, which we have already found, from the value of the segment LB (which is known by the conditions of the problem). So, KL = 2.1-0.8 = 1.3
The section length KL is 1.3.
