First consider that we increase the lengths of the sides. Then if we increase the side measuring $24$ by $x$,then the side measuring $18$ will be increased by $2x$,so $18+2x=24+x$ that is $x=6$ and the side length of the square in this case is $30$.
Now assume that the side lengths are decreased. Then if the shorter side decreases by $x$ the longer side will decrease by $2x$. From this case we have that another possible value of the side length of the square is $12$ :|
