The flower bed is shown below:
To find the remaining lenght of the flower bed (which we named c) we can use the pythagorean theorem:
[tex]c^2=a^2+b^2[/tex]where a and b are the legs of the triangle, in this case both legs are equal to 6, then we have;
[tex]\begin{gathered} c^2=6^2+6^2 \\ c^2=36+36 \\ c^2=72 \\ c=\sqrt[]{72} \\ c=8.5 \end{gathered}[/tex]Therefore the remaining length is 8.5 ft.
