If the side of an equilateral triangle is 16 cm, then what is its area ?

$81\sqrt{3} cm^2$ $48\sqrt{3} cm^2$ $32\sqrt{3} cm^2$ $64\sqrt{3} cm^2$

$64\sqrt{3} cm^2$

We know that, Area of a equilateral triangle = \(\frac{\sqrt {3}}{4}\) × (side)2 Side = 16cm Area of a equilateral triangle = \(\frac{\sqrt {3}}{4}\) × (16)2 = \(\frac{\sqrt {3}}{4}\) × 256 = $64\sqrt{3} cm^2$
