Area and Perimeter Problem Solving

The video tutorial covers solving area and perimeter word problems. It begins with a review of the formulas for area and perimeter, emphasizing the importance of reading problems carefully. The teacher walks through three example problems: calculating the width of a dog pen given its area, finding the missing side of a cake pan using its perimeter, and determining the perimeter of a barn after calculating its width. The video concludes with instructions for students to practice these problems online, noting that the practice will help prepare for an upcoming assessment.
