Area and Properties of Shapes

The video tutorial covers lesson 19 on the area of a parallelogram. It begins with identifying the vertices of parallelogram ABCD and proceeds to draw a rectangle around it, labeling triangles S and T. The tutorial explains how to calculate the area of the rectangle and the triangles, and then uses these areas to find the area of the parallelogram. It also introduces rectangle R, which shares the same base and height as the parallelogram, and includes exercises for further practice.

What are the coordinates of vertex B in the parallelogram ABCD?
