The video tutorial covers solving perimeter problems involving rectangles and word problems using algebra. It begins with an introduction to perimeter concepts, followed by step-by-step solutions to problems involving rectangles. The tutorial then addresses word problems, including scenarios with Maria and Chris's money and finding two numbers based on given conditions. The focus is on translating word problems into algebraic equations and solving them.
