Regular hexagon????????????????

A regular hexagon is formed from 6 equilateral triangles,. If
each triangle has perimeter 4, then the perimeter of the hexagon is:
8...how to solve?

Since the triangles are equilateral, all sides are the same length,
so the length of each side of each triangle is 4/3. Since each triangle has one
edge that takes part in the perimeter of the hexagon (just draw the
picture), we have that the perimeter of the hexagon is 6*(4/3) = 8.
