Area of Trapezoids and Kites

In this video, Mr. Backberg explains how to find the area of trapezoids and kites. For trapezoids, the area is calculated using the formula: 1/2 * (base1 + base2) * height. An example is provided with specific measurements to demonstrate the calculation. For kites, the area is found using the formula: 1/2 * diagonal1 * diagonal2. Another example is given to illustrate this calculation. The video concludes with a summary of the methods discussed.
