[BNM] aspect ratio guide

[Ali]

Wow thanks alex makes my answer seem kindergarten--and rightly, my solution
is making for a few problems in my flash app - got to determine the size of
a wall by how many cards there are to be hung on it and I am hacking it to
death - I'll have a go at translating your answer into actionscript.

Why did i ditch maths age 17? Need it now more than ever!

Cheers,

Ali

Ooh! simultaneous equations.

(1) w/h = 16/9
(2) w*h = x

(2) /h -> (3) w = x/h
subst (3) for w in (1) -> (4) x/h^2 = 16/9
(4) * h^2 -> (5) x = 16/9 * h^2
(5) -> (6) h = sqrt(x * 9/16)

let x = 144

h = sqrt(144 * 9/16) = sqrt(81) = 9
w = h * (16/19) = 16

let x = 1200
h = 25.98
w = 48.187

Rounding up or down is left as an exercise for the reader.
