# Area of a Triangle Calculator

In order to calculate the area of a triangle, you have to multiple the length of the base of the triangle (b) with the height or altitude of the triangle (h) and divide by 2:

**½ × b × h**

For example,

If the length of the base (b) equals 4 and the height of the triangle (h) equals 6, the area of the triangle equals 12:

½ × b × h = ½ × 4 × 6 = 12
