Well, since the scale factor is 5:6, we know that 30 goes into both 5 and 6, since we know A has to equal 30, we find out what he have to multiply the 6 by. We do this: 30/5=6
So then we multiply 6x6=36.
Therefore x has to equal 3x=36
This means that x=12
Dimension of larger rectangle × scale factor = dimension of smaller rectangle
3x*5/6=30
x=12

So 3x=36
