## Area and Perimeter of Regular Hexagon

Now, go through the below article to know the Perimeter and Area of a Regular Hexagon.

#### Perimeter of Regular Hexagon Formula

The Perimeter of a hexagon is the sum of all side lengths of it. The regular hexagon consists of 6 sides. Multiplying the side length of the hexagon with 6 gives you the perimeter of the hexagon. If you consider the side length of the hexagon as a, then the perimeter of a regular hexagon becomes P = 6 Ã— a.

The perimeter of a Hexagon = 6a.

#### Area of Regular Hexagon Formula

The area of the hexagon is the space or region inside the boundary of the hexagon. To calculate the area of the hexagon, we need to make the hexagon into six isosceles triangles. Then by calculating the area of one isosceles triangle we can multiply all the 6 triangles and can find the total area of the polygon.

##### Area of the Hexagon Formula Derivation

Firstly, take one of the triangles and draw a middle line from the midpoint of the base that forms a right angle. Let us consider the base of the triangle as a and the side length of the polygon is h.

The sum of all exterior angles present on the triangle is equal to 360 degrees. Here, âˆ POQ = 360/6 = 60Â°.

Therefore, Î¸ = 30Â°.

As we know that the tan of an angle is opposite side by adjacent side,

Therefore, tan Î¸ = (a/2)/h

tan 30 = (a/2)/h

âˆš3/3 = (a/2)/h

h = (a/2) Ã— (3/âˆš3)

The area of a triangle = bh/2

The area of a triangle = 1/2 Ã— a Ã— a/2 Ã— (3/âˆš3)

= (3/âˆš3) (a^{2}/4)

Area of the hexagon = 6 x Area of Triangle

Area of the hexagon = 6 x (3/âˆš3) (a^{2}/4)

Therefore, the area of the hexagon = 3âˆš3/2 Ã— a^{2}

### Perimeter and Area of Regular Hexagon Examples

Check out the below examples and know-how to find the area and perimeter of the regular hexagon.

**Question 1.**

Calculate the area and perimeter of a regular hexagon whose side is 8.2cm.

**Solution:**

Given that the side of the hexagon is 8.2 cm.

Area of a Hexagon = 3âˆš3/2 Ã— a^{2}

Area of a Hexagon = 3âˆš3/2 Ã— (8.2)^{2} = 174.68952 cm^{2}

Perimeter of the hexagon = 6a = 6 Ã— 8.2 = 49.2 cm

Therefore, the area = 174.68952 cm^{2} and perimeter = 49.2 cm

**Question 2.**

The perimeter of a hexagonal is 48 cm. Find the area of the board?

**Solution:**

Given that the perimeter of a hexagonal is 48 cm.

The perimeter of a Hexagon = 6a

48 cm = 6a

a = 48/6 cm

a = 8 cm.

The Area of a Hexagon = 3âˆš3/2 Ã— a^{2} = 3âˆš3/2 Ã— 8^{2} = 166.27 cm

Therefore, the Area of a Hexagon is 166.27 cm^{2} when the perimeter of the hexagon is 8 cm.

**Question 3.**

If the area of a regular hexagon is 48âˆš3 cm^{2}, find its perimeter.

**Solution:**

Given that the area of a regular hexagon is 48âˆš3 cm^{2},

Let the side of a regular hexagon be a.

The Area of a Hexagon = 3âˆš3/2 Ã— a^{2}

So, 3âˆš3/2 Ã— a^{2} cm^{2} = 48âˆš3 cm^{2},

Divide the above equation with âˆš3 into both sides.

3/2 Ã— a^{2} = 48

a^{2} = 48 Ã— 3/2

a^{2} = 72

a = 8.48 cm

Therefore, perimeter = 6a = 6 Ã— 8.48 = 50.88 cm
