Ally has a square backyard with an area of 169 square feet.

Given a square of side length, s


\text{Area of a Square}=s^2

Therefore:


\begin{gathered} s^2=169\text{ square feet} \\ \text{Take the square root of both sides} \\ √(s^2)=√(169) \\ s=13\text{ feet} \end{gathered}

Therefore, the length of one side of the backyard is 13 feet.
