Although you could do it by calculating he ratios and areas, then comparing, there’s an easier way: If every dimension is multiplied by two, every side length must also be multiplied by two, so the perimeter is doubled.

Step; This conversion of 10.03 kilometres to hectometres has been calculated by multiplying 10.03 kilometres by 10 and the result is 100.3 hectometres.-by-step explanation:
