Question 702398
<font face="Times New Roman" size="+2">


Let *[tex \LARGE s] represent the measure of the side of the original square.  Then *[tex \LARGE s\ +\ 3] is the measure of the side of the larger square.


The area of the larger square is then *[tex \LARGE (s\ +\ 3)^2], which is 69 square yards larger than the area of the smaller square which is *[tex \LARGE s^2]


Therefore


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ (s\ +\ 3)^2\ =\ s^2\ +\ 69]


Solve for *[tex \LARGE s]
