<font face="Times New Roman" size="+2">


Let *[tex \Large x] represent the short side.  Then *[tex \Large 2x] represents the long side, and *[tex \Large 3x\ -\ 48] is the third side.  The perimeter is the sum of the three sides, so:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ x\ +\ 2x\ +\ 3x\ -\ 48\ =\ 168]


Solve for *[tex \Large x] and then calculate *[tex \Large 2x] and *[tex \Large 3x\ -\ 48]

*[tex \LARGE e^{i\pi}\ +\ 1\ =\ 0]
My calculator said it, I believe it, that settles it
