Answer 1

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.
