I have never used matlab before and have no idea how to plot level curves. I looked online and most results involve using contour but not exactly sure how to specify the upper limit of z.

Your "level" curves are all ellipses and can most easily be generated by:
t = linspace(0,2*pi);
x = sqrt(c/2)*cos(t);
y = sqrt(c/5)*sin(t);
plot(x,y)
axis equal
