How to determine the area of a triangle

The video tutorial guides students through calculating the area of a triangle. It begins with identifying the type of figure and the formula for area calculation, which is 1/2 base times height. The tutorial then focuses on determining the correct base and height, emphasizing the importance of choosing a base with a known height. Finally, it demonstrates the calculation process, resulting in the area of the triangle.

Explain why certain values for the base were not suitable for calculating the area.

What is the area of the triangle if the base is 9 and the height is 6?
