Calculating Areas of Squares

The video tutorial explains how to find the area of a shaded region formed by a smaller square inscribed within a larger square. The larger square has a side length of 20 inches. The process involves calculating the area of the larger square, determining the side length of the smaller square using the Pythagorean theorem, and then finding the area of the smaller square. Finally, the area of the shaded region is obtained by subtracting the area of the smaller square from the larger square.

What is the side length of the larger square in the problem?

• 20 inches

• 25 inches

• 15 inches
