Answer:

Perimeter of given regular hexagon is 48.5 ft.

Step-by-step explanation:

Let ABCDEF be the regular hexagon as shown in the attached figure.

O be the intersection point of the diagonals EB, FC and AD.

As per the property of regular hexagon, all the 6 triangles formed are equilateral triangles.

In other words,

[tex]\triangle EOD, \triangle DOC, \triangle BOC, \triangle AOB, \triangle AOF , \triangle FOE[/tex] are equilateral [tex]\triangle s[/tex].

Area of an equilateral [tex]\triangle[/tex] is defined as :

[tex]\dfrac{\sqrt{3}}{4} \times a^{2}[/tex]

Where a is the side of [tex]\triangle[/tex].

Area of hexagon = [tex]6 \times \dfrac{\sqrt{3}}{4}\times a^{2}[/tex]

We are given that area of hexagon = 169.74 [tex]ft^{2}[/tex]

Let s be the side of hexagon.

[tex]\Rightarrow 6 \times \dfrac{\sqrt{3}}{4}s^{2} = 169.74 ft^{2}\\\Rightarrow s = 8.08 ft[/tex]

A regular Hexagon is made up of 6 equal sides, so

Perimeter of a regular hexagon = [tex]6 \times side[/tex]

Perimeter = [tex]6 \times 8.08[/tex]

[tex]\Rightarrow 48.5 ft[/tex]

So, perimeter of given regular hexagon is [tex]48.5 ft[/tex].
