A triangle of wheat fields, the bottom is 125 meters, the height is 72 meters. Last year, this land received a total of 10.8 tons of wheat, the average yield of wheat per hectare how many tons?

125 × 72 / 2, = 9000 / 2, = 4500 (M2), = 0.45 (HA); 10.8 / 0.45 = 24 (T); a: the average wheat yield per ha is 24 t
