How to find the area of a figure by using multiple figures (mistake)

The video tutorial explains how to calculate the area of complex figures by breaking them down into simpler shapes like squares, triangles, and semicircles. The instructor guides students through the process of adding and subtracting areas to find the total area of a composite figure. The tutorial emphasizes the importance of accuracy in calculations and demonstrates how to adjust methods when necessary, such as using a trapezoid instead of a triangle. The session concludes with a final computation of the total area.

What dimensions are provided for the square and the larger triangle?

How does the speaker suggest handling the smaller triangle in the area calculation?

What formula is used to calculate the area of the semicircle mentioned in the text?
