Question 331372
<font face="Garamond" size="+2">


Let *[tex \Large x] represent the measure of the height.  Then the measure of the base is *[tex \Large x\ +\ 6].


The area of a triangle is the product of the base times the height divided by 2, so:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ \frac{x(x\ +\ 6)}{2}\ =\ 56]


Solve for *[tex \Large x] to get the height, add 6 to get the base.  Note: The resulting quadratic equation will have two roots.  Discard the negative root because you are looking for a positive measure of length.

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