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?

  • Geometry -

    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.

  • Geometry -

    34.2cm^2* 6

    These answers are both wrong. It is 73.5^3cm2

  • Geometry -

    73.5^3cm2
