The video tutorial explains how to find the area of a triangle using the formula (base x height) / 2. It begins with the derivation of the formula from a rectangle and provides multiple examples to illustrate the calculation process. The tutorial also covers how to handle extra information, different units, and how to find missing dimensions when given the area. The final example involves calculating the total area for multiple triangular ornaments.

What is the formula to calculate the area of a triangle?

• Area = Base / Height

• Area = (Base x Height) / 2

• Area = Base x Height
