Group Title
A regular hexagon A has the midpoints of its edges joined to form a smaller hexagon B. This process is repeated by joining the midpoints of the edges of the hexagon B to get a third hexagon C. What is the ratio of the area of hexagon C to the area of hexagon A?

d is the side of smaller hexagon , so the length i have marked here will be d/2 dw:1350381918942:dw
