What is the expected distance of two points in a unit square?

What is the expected distance of two points in a regular unit pentagon?

Does the expected distance between two points in a regular unit n-gon converge as n goes to infinity?

Empirically, by simulation. Or do some area integrals.

For an equilateral triangle with unit sides it's 0.364791843300...
For a square with unit side it's 0.521405433....
For a circle with unit radius it's 0.905414787...
