Question
ABCDEF is a regular hexagon, and m(AD) = 12 cm. What is
the area (in cm²) of the given hexagon?Solution
ATQ, Let Understand what AD is
In a regular hexagon, opposite vertices are 2 side lengths apart in a straight line through the center. So A and D are opposite vertices. That means AD is the "diameter" of the hexagon. So, In a regular hexagon, side length s = radius of the circumscribed circle. Distance between opposite vertices = 2s. So: AD = 2s 12 = 2s s = 6 cm Area formula Area of a regular hexagon with side length s is: Area = (3√3 / 2) · s² Plug in s = 6: s² = 36 Area = (3√3 / 2) · 36 = 54√3 cm²
