Question

which of the following unit is submultiple of unit square centimetre ?
mm² dm² hm² m²

Answer 1

Answer:

So to cover a larger distance we use km(kilometre) , hm (hectometre) , and dac(decametre). These are called the multiples of Metre. When the distance is smaller , we use Dm (decimetre , cm(centimetre) and mm (millimetre) . These are called the submultiples of Metre.
