Area and Shapes in Geometry

This video tutorial explains how to find the area of a shaded region within a square. The square has sides of 2 units, and the unshaded parts form a circle. By rearranging tiles, the video demonstrates that the circle's radius is 1 unit. The area of the shaded region is calculated by subtracting the circle's area from the square's area. The tutorial concludes with the final area of the shaded region being approximately 0.86 square units.
