Why was georgia willing to give land away and not sell it

Between 1805 and 1833, the state of Georgia conducted eight land lotteries (one each in 1805, 1807, 1820, 1821, 1827, and 1833 and two in 1832) in which public lands in the interior of the state were dispersed to small yeoman farmers (i.e., farmers who cultivate their own land) based on a system of eligibility and chance. During the twenty-eight years in which the lottery operated, Georgia sold approximately three-quarters of the state to about 100,000 families and individuals for minuscule amounts of money.

Use the formula: (n-2)×180, where n is the number of sides(18-2)×180= 28800, now this is the full exterior angle of 18-gon so you divide it by 18.28800÷18=160
