Question 132
An equilateral triangle of side 6cm has its corners cut off to form a regular hexagon. Area (in cm2) of this regular hexagon will be ?
Solution
The hexagon is composed of 6 equilateral triangles, each with a side of 2.
Area of an equilateral triangle =Â $$\frac{\sqrt3}{4}s^2$$
=> Area of regular hexagon = 6 $$\times$$ area of small equilateral triangles
= $$6\times\frac{\sqrt3}{4}\times(2)^2$$
= $$6\sqrt3$$ $$cm^2$$
=> Ans - (C)
