What is the area of an equilateral triangle whose each sides is 12 cm?
Answer & explanation
Correct answer: option 1
The side of equilateral triangle = 12 cm
We know that the area of a equilateral triangle = \(\frac{\sqrt {3}}{4}\) × (side)2
= \(\frac{\sqrt {3}}{4}\) × (12)2
= $36\sqrt{3} \,\,cm^2 $
