A steel plate has an area of 0.65 square meters, a thickness of 1 cm, and a weight of 50.7 kg. If a steel plate with an area of 0.2 square meters is cut from the steel plate, what is the weight of the cut steel plate? (Solve with ratio)
一块钢板面积为0.65平方米，厚1厘米，重50.7千克，如果从钢板上切割下一块面积是0.2平方米的钢板，切下的这块钢板重多少千克．(用比例解)
