The area of a regular polygon can be found through the equation:
##A=1/2aP##
Where ##A## is the area ##a## is the apothem length and ##P## is the perimeter.
We know that ##a=303##.
We can find ##P## because we know one of the sides of the hexagon. Assuming this is a regular hexagon the perimeter will be equivalent to:
##350xx6=2100##
Plug in these values into the area equation.
##A=1/2(303)(2100)##
##A=318150##
