71dam2 25m2..............7125m2
801cm2............8dm210mm2
12km2 5hm2..............125hm2
58m2..........580dm2
Ta có:
71dam2 25m2 = 7125m2
801cm2 = 80100mm2
8dm210mm2 = 80010mm2
12km2 5hm2 = 1205hm2
58m2 = 5800dm2
Vậy ta có kết quả so sánh như sau:
71dam2 25m2 = 7125m2
801cm2 > 8dm210mm2
12km2 5hm2 > 125hm2
58m2 > 580dm2
