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.

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

• Base plus height

• Base minus height

• 1/2 base times height

• Base times height

Why can't the base of 7 be used in this scenario?
