Find the Area of a Parallelogram by Decomposing
Using the area formula makes sense, but what about when finding the area of a parallelogram? The slanted figure is decomposed in the video to show how it still applies the area formula of base times height. The video addresses common...

Find the Area of Polygons by Decomposing into Triangles, Rectangles, Parallelograms, and Trapezoids
Take a multi-sided figure, such as a pentagon, and break it into smaller shapes to calculate the area. The video demonstrates this idea visually by breaking figures into small pieces and calculating each area. Also included, is a review...
