The side length of a square is 32 cm. If one side is enlarged by 2 times and the other side is reduced by 4 times, it becomes a rectangle. How has the current graph area changed? How much did it get bigger (smaller)? Is there a clever way? Think about it and write it down!
一个正方形的边长是32厘米，如果将一条边长扩大2倍，另一条边长缩小4倍以后变成一个长方形．现在的图形面积怎么变了？变大(小)了多少？有巧方法吗？想一想写下来！
