AlekseyPX

Since you keep proportional dimensions, the proportion between the old and new dimensions must be the same. So, if we call the new height $h$ , the preservation of the width/height ratio is written as

$4 \div 6 = 9 \div h$

Solving the proportion for $h$ yields

$h = \frac{6\cdot 9}{4} =\frac{3\cdot 9}{2} = \frac{27}{2} = 13.5$
