This topic involves applying the Pythagorean Theorem to find the area of squares, given the length of their diagonals. The focus is on calculating the area from the diagonal, requiring a conversion from the hypotenuse of a right triangle (formed by the square's diagonal) to the square's side length, and subsequently finding the area. Each problem presents a different diagonal length and requires computing the square's area, presented as real numbers to practice decimal calculations. The questions vary the diagonal lengths, enhancing skills in geometry and algebra through practical application of theoretical concepts.
