Answer:
A regular hexagon has all sides of the same length, and a hexagon is a shape with six sides.
This means, if we can find the length of one side, we can find the perimeter of the entire hexagon by multiplying it by 6.
Segment FK is one side of the hexagon with endpoints at (1,2) and (4,2). From this, we can see that the length of segment FK is (4-1), or 3 units long. That means, the perimeter of the hexagon is 3 times 6, or 18 units long.
