see the figure below to better understand the problem

In the given square ABCD

Apply the Pythagorean Theoren in the right triangle BDC


\begin{gathered} D^2=a^2+a^2 \\ D^2=2a^2 \\ we\text{ have} \\ D=12√(10)\text{ ft} \end{gathered}

Substitute given value


\begin{gathered} (12√(10))^2=2a^2 \\ 144(10)=2a^2 \\ 2a^2=1,440 \\ a^2=720 \\ a=√(720)\text{ ft} \end{gathered}

Simplify


a=12√(5)\text{ ft}
