Hexagon = 6 sides
draw it out, you will form 6 isosceles triangle in the polygon.
find the interior angle of the hexagon and divide by 2 to find the base angle of the isosceles triangle.
find all the angles in the triangle.
using sine rule, find the unknown two equal sides which forms the isosceles triangle with the base 8mm.
using 1/2 ab sinC , find the area of one isosceles triangle and x6 for area of hexagon.
i will upload the answer in the next attachment!
