Calculating Area and Perimeter of Composite Shapes

This video tutorial explains how to determine the perimeter and area of composite shapes. It provides two examples, breaking down the shapes into simpler rectangles to calculate their areas. The first example involves calculating the perimeter and area of a shape with given side lengths, while the second example demonstrates a similar process with a different shape. The video encourages viewers to pause and try solving the problems independently before checking the solutions.
