Answer:
<h2>The distance between points A and B is 8.5 units, approximately.</h2>
Step-by-step explanation:
In the image attached you can observe a representation of the problem.
We have to find the distance between points A and B, which have coordinates (6,0) and (0,6), respectively.
The definition of distance between to given points is

Using points A and B, the distance between is

Therefore, the distance between points A and B is 8.5 units, approximately.
