Solution:

Note that:

  • This triangle is an equilateral triangle
  • All three angles are equal (60°)
  • All three sides are equal (12 units)
  • √3 a²/4 = Area of equilateral triangle

Using the formula, let's find the area of the equilateral triangle.

  • √3 x a²/4
  • => √3 x (12)²/4
  • => √3 x 144/4
  • => √3 x 36
  • => 36√3 units²

The area of the triangle is 36√3 units².
