\text{Area of the rectangle = 16}*9=144\operatorname{mm}
\begin{gathered} diameter\text{ of the semi circle = 16mm} \\ \Rightarrow\text{radius = 8mm} \\ \text{Area of the semicircle = }(1)/(2)*\pi*8^2=0.5*3.14*64=100.48\operatorname{mm} \end{gathered}
\text{The total area = 144+100.48=244.48 mm}^2

The area is 244.48 square meters
