Question 281565: If I have a 10" laptop screen and move up to a 12" screen size, what is the percentage of increase in size? Is there a formula that I can easily use to apply this to any size screen?

Screen area is a function of the square of the diagonal (if the aspect ratios are equal).
12 vs 10 --> 144 vs 100 in area
= 44% more area
-----------------
For a general equation:
(a/b)^2
(12/10)^2 = 1.44 times as much area
