The first step to find the area of the hexagon is to find the apothem of it by using the following formula:


a=(l)/(2tan\theta)

Where l is the sidelength and θ is half the central angle:


a=((16√(3))/(3))/(2tan30)=8

Now, find the perimeter of the hexagon by multiplying the side length by 6:


\begin{gathered} P=6\cdot(16√(3))/(3) \\ P=32√(3) \end{gathered}

Finally, find the area of the hexagon by using the following formula:


\begin{gathered} A=(P\cdot a)/(2) \\ A=(32√(3)\cdot8)/(2) \\ A=128√(3) \end{gathered}

The area of the given hexagon is 128√3
