  I lost the track of original ideas there, but one could make a
project that looks like the attached picture also to avoid the square
root.  (After setting the "origin-at-center" switch of the Playfield.)

  But maybe that was not what they want to do.  They later want to
move on to non-square cases.  The following Etoys project doesn't
provide the proof of theorem, but you can type numbers at "w = ..."
and "h = ..." and press the "goAround" button.  It shows the length of
the diagonal.
