if the ration of their sides is 2/3 then it can only be and it can not be any other way, that there perimeter is also in the ratio of 2/3.

the perimeters have the same ratio as the sides, so it is still 2/3. If it was side to area, so would square both sides of the fraction, so it would be 4/9, and so on.
