Answer 2

Answer:-

Formula to find the area of an equilateral triangle

$A = \frac{ \sqrt{3} }{4} {a}^{2}$

So now let's put the values accordingly

Area of the equilateral triangle = $\frac{ \sqrt{3} }{4} \times {6}^{2}$

$= \frac{1.7}{4} \times 36$

$= 1.7 \times 9$

$= 15.3$

So the area of the given equilateral triangle is 15.3cm²
