Homework Help: Geometry

You are planning to use a ceramic tile design in your new bathroom. The tiles are blue-and-white equilateral triangles. You decide to arrange the blue tiles in a hexagonal shape as shown. If the side of each tile measures 7 centimeters, what will be the exact area of each hexagonal shape?

It takes 6 equilateral triangles to make a hexagon. Each equilaterial triangle area is
A = (1/2)(base)*(height)
= (1/2)(7)*(7 cos30)
= 34.2 cm^2

Multiply that by 6

I don't get the significance of the blue and white pattern.
