[tex]P_{Garden}=96.26ft[/tex]
1) We need to find the Perimeter of this shape, since there are three sides of a rectangle, and one semi-circle we can write out the following
[tex]\begin{gathered} P_{Semicircle}=\frac{2\pi r}{2}=\pi r \\ P_{rectangular\:part\:}=25+25+18 \end{gathered}[/tex]
Note: The radius is equal to half that vertical leg.heual
2) So now, let's add them up and approximate pi as 3.14
[tex]P_{Garden}=25+25+18+(3.14)(9)=96.26ft[/tex]
