Understanding Perimeter and Area of a Square

The video tutorial explains how to find the perimeter of a square given its area. It starts by describing the properties of a square and introduces the formulas for area and perimeter. The tutorial then demonstrates how to solve for the side length using the square root of the area. Finally, it calculates the perimeter by multiplying the side length by four and verifies the solution, emphasizing the importance of showing work.
