Question 280165
<font face="Garamond" size="+2">


*[tex \Large 2x\ +\ 25] and *[tex \Large 2x\ +\ 40] are the outer dimensions of the ENTIRE patio PLUS the strip around the outside.  504 square feet is the area of JUST the strip.  Try solving:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ (2x\ +\ 25)(2x\ +\ 40)\ =\ 504\ +\ (25\,\cdot\,40)]


And see if that doesn't give you a more reasonable answer.  Write if you are still having difficulty.
