Question 1064652
The coordinates of the vertices of a polygon are A(-2,-2), B(3,-3), C(4,-6), 
D(1,-6), and E(-2,-4)
---------------
Find the length of each side, then add them.
eg, for AB:  A(-2,-2), B(3,-3)
{{{s = sqrt(diffy^2 + diffx^2) = sqrt(5^2 + 1^2) = sqrt(26)}}}
-----------
Find the other sides, then add them.
