The Solution:
Given the figure below:
So,
[tex]\text{ Given that }FH=12,\text{ then HG=12}[/tex][tex]\begin{gathered} \text{Given that EK}=6,\text{ then} \\ KH=\frac{EK}{2}=\frac{6}{2}=3 \end{gathered}[/tex][tex]\begin{gathered} \text{Given that FI}=18,\text{ then} \\ KI=\frac{2}{3}\times FI=\frac{2}{3}\times18=2\times6=12 \end{gathered}[/tex][tex]\begin{gathered} \text{ Given that JK=4, then} \\ KG=2\times JK=2\times4=8 \end{gathered}[/tex]
