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. 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 .
Solution 2
Solution 2 has the exact same solution as Solution 1 denoted, but instead, we do not need to know the value of the apothem. We could just apply s, which is the side length in this problem, into the hexagon area formula,
