Think of laying out the 3 given sides in a straight line
to get a sum of 2011+2012+2013 = 2036
As long as x is < 2036 you will be able to "kink" the 3 lines at their joints and form a quad.
If x = 2036, they will all lie on a straight line.
if x > 2036, you can't join the end of that long side to the end of the others
so x < 2036
