Question : Find the area of an equilateral triangle whose sides are 12 cm.
Option 1: $38 \sqrt{3} \mathrm{~cm}^2$
Option 2: $35 \sqrt{3} \mathrm{~cm}^2$
Option 3: $34 \sqrt{3} \mathrm{~cm}^2$
Option 4: $36 \sqrt{3} \mathrm{~cm}^2$
Correct Answer: $36 \sqrt{3} \mathrm{~cm}^2$
Solution : Side of triangle $= 12 \ \text{cm}$ Area of an equilateral triangle $= \frac{\sqrt{3}}{4} \times \text{Side}^2= \frac{\sqrt{3}}{4} \times 12 \times 12= 36\sqrt{3} \ \text{cm}^2$ Hence, the correct answer is $ 36\sqrt{3} \ \text{cm}^2$.
