Problem 1
<h3>Answer:
6.7</h3>
----------------
Work Shown:
The two points are
and 
Apply the distance formula to get the following

The distance between the two endpoints is roughly 6.7 units. This is the same as saying the segment is roughly 6.7 units long.
======================================================
Problem 2
<h3>Answer: 3.6</h3>
----------------
Work Shown:
We'll use the distance formula here as well.
This time we have the two points
and 
The distance between them is...

This distance is approximate.
