If the triangle is equilateral, then according to the property all its angles are equal to 60º, since 180º is evenly distributed over 3 angles.
The area of a triangle can be found using the formula:
S = a * b * sin (α).
a = b = 12.
α = 60º.
S = 12 * 12 * sin (60º) = 144 * (√3 / 2) = 72 * √3.
Answer: 72 * √3.
