Finding the Missing Side from Area Problems

The video tutorial covers how to find the missing side of a rectangle when given one side and the total area. It begins with a review of area and perimeter concepts, followed by three sample problems demonstrating how to solve for missing dimensions using the area formula. The tutorial concludes with a preview of the next lesson on finding missing sides using perimeter and instructions for a follow-up quiz.

What is the formula for the area of a rectangle?

• Area = Length - Width

• Area = Length * Width

• Area = Length / Width
