[1] What is the mean distance between two random points on the perimeter of a unit square?

[2] What is the mean distance between two random points on the interior of a unit square?

(In reply to re(2): Part 2 in two different ways. by Charlie)

I actually got those counts but I added them using an unfamiliar calculator so I don't doubt I mis-entered somewhere. 

Thanks for validating my idea.

Incidentally, you can find many web pages that include the correct solution - using integration - and also a few that use my incorrect assumption.
