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.
