Yes, I know that :) But what was the first and last point you went to?

Physics takes some imagination. You should always help your imagination out by drawing a picture, but this one is easier than you think. (here's a hint: the perimeter of the field is irrelevant)

Yep. If you got exactly twice around something that's the same as going exactly once around  you'll end up in the exact same place you started from.

You know the distinction between distance and displacement?
