Calculating Perimeter of Polygons

This video tutorial focuses on solving perimeter problems using polynomials. It begins with an introduction to the concept of perimeter and its application in various shapes. The tutorial covers three main problems: finding the side length of a square given its perimeter, determining the missing side of a triangle, and solving for a missing side in a four-sided polygon. Each problem is explained step-by-step, emphasizing the use of polynomial operations. The video concludes with a prompt for independent practice, encouraging viewers to apply the learned concepts.
