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(s-a)(s-b)(s-c))

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.
