Geometry: Area and Perimeter Problems

Maria and her mascot Maty introduce the concepts of area and perimeter, explaining how to calculate them for rectangles and more complex shapes. The lesson includes examples of calculating area using multiplication and perimeter by adding side lengths. The video also covers drawing rectangles with specific areas and solving a puzzle involving area and perimeter.
