Adjoining regular hexagons

Find the perimeter of a regular hexagon, having six sides of equal length (6 units).

Attach another regular hexagon on one side, like you would see in a row of honeycomb, and find the perimeter of the new shape (10 units).

Continue this pattern, and put your information into a table (see handout below).

What patterns do you see?

How is the perimeter growing at each new stage?

What is each perimeter compared to the number of hexagons?

See the attached 5-min. Video from the Math for Adults Foundation youtube page for the answer!
