Finding the Side Length of a Square Given the Area

The video tutorial explains how to determine the side length of a square when given its area. It covers the basic formula for calculating the area of a square and provides examples with different areas, such as 36 cm², 80 in², 100 cm², and 42 in². The tutorial demonstrates how to use variables to represent side lengths and employs estimation techniques for non-perfect squares. The key takeaway is that the side length of a square is the square root of its area.
