Question

Find the area of an equilateral triangle if each side is 8

Answer 1

= s^2√3 / 4
= (8)^2 × √3 / 4
= 64√3/4
= 16√3 or. 27.712

Answer 2

Heyaaa...

In Heron's formula, there is a simple formula to find the area of an equilateral triangle..

It is
$\sqrt{3} \div 4 {a}^{2}$
So, Let's substitute 8 in the place of a..

$\sqrt{3} / 4 * {8}^{2}$

$\sqrt{3} / 4 * 64$

Let's apply the value of $\sqrt{3}$

1.73 / 4 * 64 ( approx.)

110.72 / 4 ( approx.)

27.68 ( approx.)

Hope it helps...

So 27.68 is the area of the equilateral triangle...
