In a trapezoidal rice test field, the upper base is 200 meters, the lower base is 360 meters, and the height is 300 meters. If 6 tons of wheat are harvested per hectare, how many tons of wheat will be harvested in this experimental field?
一块梯形水稻试验田，上底是200米，下底是360米，高是300米，如果每公顷收小麦6吨，这块试验田约收小麦多少吨？
<gadget id="calculator">200 + 360</gadget>
<output>560</output>

<gadget id="calculator">300 / 2 / 10_000</gadget>
<output>3/200 = around 0.015</output>

<gadget id="calculator">6 * 560 * (3/200)</gadget>
<output>252/5 = around 50.4</output>

<result>252/5 = around 50.4</result>
