The composite figure is made by: 2 right triangles and 1 semicircle. Or 1 triangle and 1 semicircle. With any of the two combinations of shapes the area is the same.

To find the area you sum the area of each shape that compose the figure:

1 triangle and 1 semicircle:


\begin{gathered} A=A_(\Delta)+A_s \\ \\ A=(1)/(2)b\cdot h+(1)/(2)\pi\cdot r^2 \end{gathered}

As the given figure has the diameter of the circle you find the radius as follow:


\begin{gathered} r=(d)/(2) \\ r=(14m)/(2) \\ r=7m \end{gathered}

The base of the triangle is 14m and the height is 10m.


\begin{gathered} A=(1)/(2)(14m)(10m)+(1)/(2)\pi(7m)^2 \\ \\ A=(140)/(2)m^2+(49\pi)/(2)m^2 \\ \\ A=70m^2+76.97m^2 \\ \\ A=146.97m^2 \end{gathered}

The area of the composite figure is 146.97 square meters
