Answer:
The area of a triangle can be calculated using the formula:
Area = (1/2) * base * height
where the base and height are known. Alternatively, if the lengths of all three sides of the triangle are known, then the area can be calculated using Heron's formula:
Area = sqrt(s * (s - a) * (s - b) * (s - c))
where a, b, and c are the lengths of the sides and s is the semiperimeter of the triangle.
