If the side of an equilateral triangle is 24 cm, then what is its area?

169$\sqrt{3}$ cm2 125$\sqrt{3}$ cm2 256$\sqrt{3}$ cm2 144$\sqrt{3}$ cm2

144$\sqrt{3}$ cm2

Area of a equilateral triangle = \(\frac{\sqrt {3}}{4}\) × (side)2 Side = 24 cm Area of a equilateral triangle = \(\frac{\sqrt {3}}{4}\) × (24)2 = \(\frac{\sqrt {3}}{4}\) × 576 = 144$\sqrt{3}$ cm2
