Webb15 years ago. Just to add, this can be proven in 2 steps. 1) Take a polygon of n sides. Prove that the A/P ratio is largest when this polygon is regular. 2) Then for regular polygons, prove that the A/P ratio increases with n. As n --> ∞, the polygon tends to a circle and the ratio tends to r/2.
