If the rectangle has a height () to width () ratio of 3:4.5:
We can find other dimensions that fit this relation by multiplying the same number in the numerator as in the denominator.
For example:
If we multiply by :
As we can see gives ues the same result as
Another example:
If we multiply by :
As we can see gives ues the same result as
