Calculation of the Area of a Regular Hexagon - Let's Calculate It This Way!

The regular hexagon belongs to the family of regular polygons. It is a polygon in which all sides, and all angles, are equal to each other. By its name, we can understand that it is a geometric figure with 6 6 different sides. The sum of its internal angles equals 720o 720^o degrees. Therefore:

external angle =60o =60^o ; internal angle =120o =120^o

Exercise #1

Below is a hexagon that contains a rectangle inside it.

The area of the rectangle is 28 cm².

777

What is the area of the hexagon?

Video Solution

Step-by-Step Solution

Since we are given the area of the rectangle, let's first work out the length of the missing side:

7×a=28 7\times a=28

We'll now divide both sides by 7 to get:

a=4 a=4

Since all sides are equal in a hexagon, each side is equal to 4.

Now let's calculate the area of the hexagon:

6×a2×34 \frac{6\times a^2\times\sqrt{3}}{4}

6×42×34 \frac{6\times4^2\times\sqrt{3}}{4}

Finally, we simplify the exponent in the denominator of the fraction to get:

6×4×3=24×3=41.56 6\times4\times\sqrt{3}=24\times\sqrt{3}=41.56

Answer

41.56
