Given:


a=4√(3)

To find:

The area of the figure

Solution:

The given figure is regular hexagon.

Number of sides = 6

Using apothem formula:


$a=(s)/(2 \tan \left((180^\circ)/(n)\right))

where a is apothem, s is side length and n is number of sides of the polygon.


$4√(3) =(s)/(2 \tan \left((180^\circ)/(6)\right))

Multiply by 2 on both sides.


$8√(3) =\frac{s}{ \tan {30^\circ}}


$8√(3) =(s)/( (1)/(√(3) ) )


$8√(3) =\frac{s{√(3) }}{ 1 }

Cancel the common factor
√(3) on both sides, we get


8=s

Side length of the polygon = 8 units

Area of the polygon:


$A=(1)/(2) * ( \text {apothem }* \text{ perimeter})


$A=(1)/(2) * ( 4√(3) * 6* 8)


$A=96√(3)

A = 166.27 in²

The area of the figure is 166.27 in².
