Ls can be found below
[tex]\begin{gathered} LS=\frac{2}{3}LQ \\ SQ=22 \\ LS=\frac{2}{3}(22+LS) \\ \text{LS}=\frac{44}{3}+\frac{2}{3}LS \\ LS-\frac{2}{3}LS=\frac{44}{3} \\ \frac{3LS-2LS}{3}=\frac{44}{3} \\ \frac{LS}{3}=\frac{44}{3} \\ \text{cross multiply} \\ 3LS=132 \\ LS=\frac{132}{3} \\ LS=44 \end{gathered}[/tex]
