Exploring Area and Perimeter of Composite Shapes

The video tutorial covers the concepts of area and perimeter of composite shapes. It begins with an introduction to composite shapes, explaining how they are formed by combining multiple shapes. The tutorial then provides detailed steps to calculate the area and perimeter of these shapes, using examples to illustrate the process. Students are encouraged to pause and take notes as needed. The video concludes with practice problems for students to apply what they've learned.
