If the ratio of the height to the length is 1 to 6, we can write the following equation:


(height)/(length)=(1)/(6)

The height is equal to 30 ft, so let's solve the equation for the length:


\begin{gathered} (30)/(length)=(1)/(6)\\ \\ length=30\cdot6\\ \\ length=180\text{ ft} \end{gathered}

The length is equal to 180 ft, therefore the correct option is the fourth one.
