Understanding Perimeter of Composite Figures

In this video, Scout explains how to calculate the perimeter of composite figures, which are shapes made up of more than one basic shape. Using the example of a yard shaped like a rectangle and a square, Scout demonstrates how to add the lengths of the outer sides to find the total perimeter. The video emphasizes that only the outer side lengths are needed for perimeter calculations, regardless of the shape's complexity. The total perimeter of the example yard is calculated to be 53 feet.
