Question 328469
<font face="Garamond" size="+2">


The area of a rectangle is given by


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ A\ =\ lw]


So if you know the area and the width, you can calculate the length by


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ l\ =\ \frac{A}{w}]


In this case:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ l\ =\ \frac{x^2\ +\ 50x}{x}]


Simplify and you have your answer.
