Question 746554
<font face="Times New Roman" size="+2">


If you are expecting to assign a specific number to the value of the perimeter of your rectangle, you are doomed to disappointment.  The best you can do is create an expression in *[tex \LARGE w] that represents your perimeter.  The perimeter of a rectangle is two times the length plus two times the width, thus:


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


But since you know that *[tex \LARGE l\ =\ 2w\ +\ 3], you can substitute and so define the perimeter as a function of the width:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ P(w)\ =\ 2(2w\ +\ 3)\ +\ 2w]


You will need to simplify the expression yourself.  And, just as an 'oh by the way', it darned well better have four right angles, otherwise you had better stop calling it a rectangle.
