What is the area of an equilateral triangle whose each side is 14 cm long?

Side length of the equilateral triangle (a) = 14 cm

The area of an equilateral triangle with side length a;

Area = $$\frac{\sqrt{3}}{4} a^2$$​​

Substituting a = 14 cm into the formula:

​$$\text{Area} = \frac{\sqrt{3}}{4} \times (14)^2$$​​

​$$\text{Area} = \frac{\sqrt{3}}{4} \times 196$$​​

​$$= 49\sqrt{3} \text{ cm}^2$$​​

Therefore, Area of the equilateral triangle is $$\bf 49\sqrt{3} \text{ cm}^2.$$​​
