人教版数学四年级上册第2单元《公顷和平方千米》真题同步练习2(含解析)

人教版数学四年级上册第2单元《公顷和平方千米》真题同步练习2（含解析）人教版数学四年级上册第2单元《公顷和平方千米》真题同步练习2（含解析）一、判断题1．（2023四上·京山期末）育红小学的面积好大呀！大概有6平方千米。

（）2．上海市的面积大约是6340公顷3．（2023四上·祁东月考）因为边长是1000米的正方形土地面积是1平方千米，所以1平方千米的土地只能是边长是1000米的正方形．（）4．（2023四上·江门月考）200公顷=2平方千米=2000000平方米。

（）5．一条路宽10米，那么这条路每1千米占地1公顷。

（）二、填空题6．（2023四上·大洼期中）计量比较大的土地面积，常用和作单位。

7．（2022五上·连云港月考）在横线上填上合适的数。

42公顷＝平方米50000平方米＝公顷。

6000公顷＝平方千米50平方千米＝公顷。

7平方千米＝公顷＝平方米。

8．测量和计算大的面积，常用和作单位。

9．在横线上填合适的面积单位。

课桌的面积大约是40；教室的面积大约是54；校园面积大约是 3 ；江苏省的面积大约是10万。

10．填上合适的单位名称．（1）一个长方形操场长80米，宽50米，这个操场的占地面积是4000．（2）我国的陆地面积大约是960万．11．（2023四上·兴义期末）在横线上填上“>”“、90000平方米；210×30=6300>630；12亿>120000000；7公顷=70000平方米>700平方米；209÷19=11。

故答案为：；>；>；<；=。

【分析】比较不同位数的数的大小，位数多的这个数就大，位数少的这个数就小；比较位数相同的数的大小，先从最高位开始比起，最高位上的数大的，这个数就大，最高位上的数相等，就比较次高位上的数，依次进行比较。

1平方千米=1000000平方米；1公顷=10000平方米。
