Question 199764
<font face="Garamond" size="+2">


Let *[tex \Large x] represent the width, then *[tex \Large x + 8] represents the length, so:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ x(x + 8) = 84]


Distribute, put into standard form, and then solve the resulting quadratic.  Exclude the negative root. The positive root is the width and the length is 8 more inches.


Alternatively, you could calculate the area represented by each of the pairs of dimensions given in the 4 choices and select the one that results in 84 square inches.
