Answer:

The length of the side of the square is 17 ft.


l=17ft

Step-by-step explanation:

The Area of a square can be calculated using the formula;


A=l^2

Given that the area of the square is 289 sq ft, we can calculate the length of the sides by substituting the value of area A into the formula and solve for l;


\begin{gathered} A=l^2 \\ 289=l^2 \\ \text{square root both sides;} \\ l=\sqrt[]{289} \\ l=17 \end{gathered}

Therefore, the length of the side of the square is 17 ft.


l=17ft
