In this generic scenario, there is a settlement protected by both an inner and outer walls. The inner wall protects an area of 72 hectares. Both walls are 40 feet tall and thick and made of brick. Also, the walls extend to resemble both a twelve-point star and an accompanying dodecagon. In times of war, and before the cannon makes these walls obsolete, which shape would the inner wall be for maximum defense against attack?
The twelve-point star?
Or the accompanying dodecagon?
