Question

The area (in square units) of a regular hexagon of the side of $2$ units each is:

• A. $8.2$
• B. $10.4$
• C. $12.5$
• D. $18.7$

Answer 1

Answer: (B)

$10.4$

Side of hexagon $=$ $2$ units
$\therefore$ Area of hexagon $=\frac{3\sqrt{3}}{2}(a{)}^2$ {$a$ = side of hexagon}

$=\frac{3\sqrt{3}}{2}(2{)}^2=6\sqrt{3}$

$=6\times 1.73205$

$=10.3923$

$=10.4$ sq. units (approx.)
