Hey dude,
you can find all the rectanlge with the formula l = length and w = width as l = (-2w)/(2 - w).

4x4 is the other one.
Perimeter = 2a + 2b
Area = ab
2b = ab - 2a
2b = (b-2)a
a = 2b/(b-2)
I think you would take the derivative, but this is giving me a headache.

2x9 is the same as 3x6.
What about 3x10 and 2x15?
The list is endless.
