Question 497614
<font face="Times New Roman" size="+2">


Divide 1320 by the given height.  That will give you the area of the base.  You misused "base" since that would refer to the entire rectangle that has a length and a width.  I'm going to presume that you meant length is 5 inches longer than the width.


Let *[tex \Large w] represent the width.  Then *[tex \Large w\ +\ 5] represents the length.  And let *[tex \Large A] represent the area you calculated in the first step.  Then:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ w(w\ +\ 5)\ =\ A]


Simplify and solve the resulting quadratic for *[tex \Large w], then calculate *[tex \Large w\ +\ 5].


Hint:  The quadratic is factorable:  -6 times 11 is -66.

My calculator said it, I believe it, that settles it
