1/2 * base * height
(* equals multiplication)
For example:
So a triangle with a base of 10 in and a height of 5 in
10 * 5 = 50
50 * 1/2 = 25 in. squared

if a , b , c are three sides of a triangle
a = side1
b = side 2
c = base
the say h = ht
h = sqrt [a^2 + (c/2)^2]
thus by the formula of the area = 1/2 * base * ht
area = 1/2 * c * h
= 1/2 * c * sqrt [a^2 + (c/2)^2]
so just substitute the values in the above formula & calculate

A = 1/2 * a b sin(C)
where a and b are sides and C is the angle between them.
So for a right angle triangle its A = 1/2 * a b.

When asked to find the area of a triangle with only the length of the sides given, the formula is:
Area = sqrt(s*(s-a)*(s-b)*(s-c)) where s=(a+b+c)/2 and this is known as the semi-perimeter.

1/2base x height = area

Assuming you only have the length of the sides,
Let s = (a + b + c)/2
then A = sqrt(s(s-a)(s-b)(s-c))
