Given data:
The given composite figure.
The given radius is r=(7 m)/2 =3.5 m.
The length of the rectangle is,
[tex]\begin{gathered} L=18\text{ m-2(3.5 m)} \\ =18\text{ m-7 m} \\ =11\text{ m} \end{gathered}[/tex]
The area of the given figure is,
[tex]\begin{gathered} A=(11\text{ m)(}7\text{ m)-2(}\frac{1}{2}\pi(3.5m)^2) \\ =77m^2-\pi(3.5m)^2 \\ =77m^2-38.4845m^2 \\ =38.5155m^2 \\ \approx38.51m^2 \end{gathered}[/tex]
Thus, the area of thhe composite figure is 38.51 sq-meter.
