You can find the area of triangle ABC using the formula for the area of an equilateral triangle, (A = \frac{\sqrt{3}}{4} \times \text{side}^2), where the side length is 6 cm. Since triangle ABC is equilateral due to its angles, you can substitute 6 cm into the formula to find the area. Thus, the area of triangle ABC is (A = \frac{\sqrt{3}}{4} \times 6^2 = 9\sqrt{3} , \text{cm}^2).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
