The sketch of the required fence is given below:
The total length required for the fence is = 6+6+6+6=24 meters
If 10 meters is already available, then what will be required is
[tex]\begin{gathered} 24\text{meters}-10\text{ meters} \\ =14\text{ meters} \end{gathered}[/tex]Thus, 14 meters more is required for the fence
