Answer:
If you join the six vertices of a regular hexagon to its centre you will get 6 congruent equilateral triangles whose length of sides is same as that of the hexagon.
And we know the area of an equilateral triangle of side a is {(√3)/4}a^2.
Hence, area of the given hexagon = 6{(√3)/4}6^2 = 54√3 cm^2.
