Calculating the Area of a Right-Angle Triangle:

The area of a right-angle triangle can be calculated according to the following formula:

A = 1/2(bh)

In plain english the area of a right angle triangle can be calculated by taking one half of the base multiplied by the height.

Below is an example of how to find the area of a right-angle triangle with a base of 6 meters and a height of 3 meters.

  • A = 1/2(bh)
  • = 1/2(6 * 3)
  • = 1/2(18)
  • = 9
