Answer 2

SOLUTION:-

Given:

An equilateral triangle with side 8cm.

Therefore,

We know that, area of equilateral ∆;

$= > \frac{ \sqrt{3} }{4} ( {a})^{2}$

So,

$= > \frac{ \sqrt{3} }{4} \times 8 \times 8 \\ \\ = > \sqrt{3} \times 2 \times 8 \\ \\ = > \sqrt{3} \times 16 \\ \\ = > 1.732 \times 16 \\ \\ = > 27.71 {cm}^{2}$

Thus,

Area of equilateral triangle is 27.71cm².
