Solution
Let the backyard be
We want to find x
By pythagoras theorem
[tex]\begin{gathered} Hypotenus^2=Opposite^2+Adjacent^2 \\ x^2=24^2+45^2 \\ x^2=576+2025 \\ x^2=2601 \\ x^{}=\sqrt[]{2601} \\ x=51\text{meters} \end{gathered}[/tex]
Therefore, the length of the diagonal chicken wire fence will be 51 meters
