In order to accomplish that assignment, you might suspect that a person 
needs to know something about the figure ... things like maybe what shape 
it is, and what a few of its measurements are.  You would be absolutely correct 
too. I've looked over your question, and found that you haven't included a single 
shred of information about the figure.  I don't know if it's a square that can fit in 
the bottom of my coffee cup, or a circle that the Earth can fit through.  If I see it 
walking around on the street tomorrow, I won't even recognize it.  Although I do
crave to solve the problem and answer your question, I have nothing to get to
Square-1 with.  I'm sitting here at  Square-0 , looking for information to use in
my calculations.
