We know that
• The radius is 17 feet.
First, we find the circular area
[tex]\begin{gathered} A=\pi(r)^2 \\ A=3.14(14)^2\approx3.14\cdot196\approx615.44ft^2 \end{gathered}[/tex]This means the square flower bed will have an area of 615.44 square feet. So, we find its sides with the formula for squared areas
[tex]\begin{gathered} A=l^2 \\ 615.44=l^2 \\ l=\sqrt{615.44}\approx24.808 \end{gathered}[/tex]
