It all depends on what is given.
If the base and the area are given, then you can solve for h in
Area=base*height
If the three sides of a triangle are given, you would have to calculate the area of the triangle first using
s=(a+b+c)/2
Area=sqrt(s(sa)(sb)(sc))
If angles and sides are given, you'd have to solve for the triangle using sine rule, cosine rule, or other trigonometric formulae.
Good luck on your exam.
