Answer:
it depends on what data you start with
Step-by-step explanation:
The usual formula for the area of a triangle is ...
A = (1/2)bh
where b represents the base length of the triangle, and h represents the altitude to that base (the height).
__
If you are given two side lengths, a and b, and the angle C between them, the area can be found using the formula ...
A = (1/2)ab·sin(C)
__
If you are given the three side lengths, a, b, c, then the area can be found using Heron's formula:
A = √(s(s -a)(s -b)(s -c))
where s is the semi-perimeter: s = (a+b+c)/2.
