METHOD
[tex]\begin{gathered} \text{Area of a square = L}^2 \\ \text{Area of a rectangle = L x W = LW} \end{gathered}[/tex]Next
[tex]\begin{gathered} \text{Area of square - area of rectangle }>\text{ 0} \\ L^2\text{ - LW }>\text{ 0} \\ \text{next, factor L out} \\ L(L\text{ - W) > 0} \\ L\text{ > 0 or L - W > 0} \\ L\text{ > 0 or L > w} \end{gathered}[/tex]The two possible side length of Lena square
is
L > 0 or L > W
