Answer 2

Explanation:

the SI unit of length is metres. when a larger distance is to be covered, we cannot use metre. So to cover a larger distance we use km( kilometers) , hm( hectometre) , and dac( dacametre) . these are called the multiples of metres. when the distance is smaller we use Dm ( decimetre) , cm ( centimeter) and mm( millimetre) . these are called the sub multiples.
