Finding the Perimeter of Composite Figures

The video tutorial introduces composite figures, which are made up of two or more two-dimensional shapes like triangles, squares, rectangles, and circles. It explains how to calculate the perimeter of these figures by finding the total distance around them, using examples such as a house and a window. The tutorial includes practice problems involving semicircles, rectangles, triangles, and squares, demonstrating how to calculate the perimeter by combining the circumferences and side lengths of these shapes.

What is the formula for finding the circumference of a circle?

What is the final perimeter of the composite figure that includes two semicircles and a rectangle?

How do you determine the total perimeter when dealing with a semicircle and additional sides?
