Question

4. Side of a regular hexagon is 12 cm. Find its area.​

Answer 1

Answer:

hexagon has 6 sides

Step-by-step explanation:

so 12×6=72

Answer 2

The area of a regular hexagon = $216\sqrt{3}$$cm^2$ or 374.112 $cm^2$

Step-by-step explanation:

Given,

The side of a regular hexagon(a) = 12 cm

To find, the area of a regular hexagon = ?

We know that,

The area of a regular hexagon = 6 × The area of a equilateral triangle

= 6  × $\dfrac{\sqrt{3}}{4}a^{2}$

= $6\times \dfrac{\sqrt{3}}{4} \times 12 \times 12$

= $6\times \sqrt{3} \times 3 \times 12$

= $216\sqrt{3}$$cm^2$

= 216 × 1.732 $cm^2$

= 374.112 $cm^2$

Thus, the area of a regular hexagon = $216\sqrt{3}$$cm^2$ or 374.112 $cm^2$
