The document describes the areas of two squares - a big square with sides of 5 inches and an area of 25 inches squared, and a small square with sides of 3 inches and an area of 9 inches squared. It then uses the pattern of the sum and difference of two binomials to calculate the difference between the areas, finding that the big square's area minus the small square's area equals 25 - 9 = 16 inches squared.
