Problem
Regular hexagon has vertices and at and , respectively. What is its area?
Solution
To find the area of the regular hexagon, we only need to calculate the side length.
Drawing in points , , and , and connecting and with an auxiliary line, we see two 30-60-90 triangles are formed.
Points and are a distance of apart. Half of this distance is the length of the longer leg of the right triangles. Therefore, the side length of the hexagon is .
The apothem is thus , yielding an area of .
