Question 335155
<font face="Garamond" size="+2">


Let *[tex \Large x] represent the measure of the width.  Then *[tex \Large x + 3] represents the measure of the length.


The formula for the perimeter is:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ P\ =\ 2l\ +\ 2w]


Substitute the expressions we defined for length and width and the value for the perimeter and then solve for *[tex \Large x].

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