So you thought "hey they added 2 to each side, they must be similar"

For similarity, we're looking for `multiplication` which gets us from one shape to the other, not addition.

oh, well I just looked at the two shapes and guessed if it was similar. xD

yes it would be A because 8/2=4  
9/2=4.5
6/2=3

zepdrix · Answer

So in order to get from the 6 to the 8,
we have divide by 3,
$\large\rm 6\div3=2$
and then multiply by 4,
$\large\rm 2\times4=8$

But if we try that with other side,
$\large\rm 14\div3=4.7$
$\large\rm 4.7\times4=18.7$

So the longer side should be 18.7, not 16.
