Question

Any idea on how to do this? I'm a little confused.

Answer 1

12

Explanation:

You are given two lines, the blue one and the one with the letters and are told to find the length of UV (which would just be from point U to point V)

The blue line seems to represent the total length of the black line and the length of VW is already shown. Since the total length is 16 and we alredy know that VW is 4, we'll subtract the two to find the length of UV

Which would be: 16-4=12

Answer 2

Answer is 12.

Explanation:

If UW is 16, and VW is 4, then just do 16-4 to get 12.

Hope this helps.
