1   Pass
xy=[0,0; 1,0; 1,1; 0,1; 0,0]; err=(abs(perimeter1(xy)-4)/(4))*100; assert(err<.1)

L = 4
2   Pass
t=[0:pi/100:2*pi,0]'; xy=[cos(t),sin(t)]; err=(abs(perimeter1(xy)-2*pi)/(2*pi))*100; assert(err<.1)

L = 6.2829
3   Pass
t=[0:pi/100:pi,0]'; xy=[cos(t),sin(t)]; err=(abs(perimeter1(xy)-(pi+2))/(2+pi))*100; assert(err<.1)

L = 5.1415
4   Pass
side=rand; x=side*[-1 -0.5 0.5 1 0.5 -0.5 -1]; y=side*sqrt(3)*[0 -0.5 -0.5 0 0.5 0.5 0]; xy=[x',y']; err=(abs(perimeter1(xy)-(6*side))/(6*side))*100; assert(err<.1)

L = 4.9510
