Geometry: Coordinates and Rectangles

The video tutorial explains how to find the perimeter of a rectangle ABCD using its vertices. It begins by introducing the problem and explaining the concept of vertices. The instructor then demonstrates how to plot the points on a coordinate plane and connect them to form the rectangle. The video concludes with a step-by-step calculation of the perimeter, resulting in a final answer of 22 units.
