1.75x = 9
2.25x = 12

Solve for x

which are 5.1 AND 5.3 respectively
So one inch ~ 5.2 ft

Hi. Just divide. 9 feet is 12x9 inches, or 108. 108/1.750 = the scale. You will find that 12 X 12 =144 and 144 / 2.25 = 64, and is not the same value.

Distorted.
Your aspect ratio changed.
9 : 12 = 3 : 4
is not the same as
1.75 : 2.25 = 7 : 9
