Depends on what information you've been provided.
If you've been provided the BASE and the HEIGHT/altitude, you can find the area of any type of triangle (equilateral, isosceles, scalene) by using this formula:
A = 1/2 bh
If you've been provided the HEIGHT ONLY, you can still find the area because it's an equilateral triangle. Simply divide it into two 30-60-90 triangles and find the short side of one of them by dividing the height (the long side of the triangle) by √3. Multiply that number by 2 to find the length of the base, then use the above formula.
If you've been provided with the SIDE, the same principles of 30-60-90 triangles apply. You can use the formula below:
A = (S2 √3) /4
If you've been provided the APOTHEM, use the following formula:
1/2 ap (where a is the apothem and p is perimeter)
This formula works for all regular polygons.
