Question 260985
<font face="Garamond" size="+2">


The perimeter of a rectangle is given by:


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


But we are given that:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ l\ =\ 4w]


and the perimeter is 90, so:



*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 2(4w)\ +\ 2w\ =\ 90]


Just solve for *[tex \Large w]
