The area of a parallelogram can be calculated using the formula: Area = base * height. The base is 5 - 0 = 5 and the height is 3. Therefore, area = 5 * 3 = 15.

Area = (d1 * d2) / 2 = (10 * 24) / 2 = 120.

The area of a rhombus can be calculated using the formula: Area = 1/2 * d1 * d2. Therefore, area = 1/2 * 10 * 24 = 120.

The area of a rectangle is calculated as length times width. The length is 4 - 1 = 3 and the width is 5 - 2 = 3. Therefore, area = 3 * 3 = 9.

Area = (d1 * d2) / 2 = (8 * 6) / 2 = 24.

Area = 1/2 * base * height = 1/2 * 6 * 4 = 12.

The length of the diagonal can be calculated using the distance formula between (2, 1) and (5, 4). Diagonal = √((5-2)² + (4-1)²) = √(3² + 3²) = √18 = 3√2.

The side length of the square is 5 - 1 = 4. Therefore, perimeter = 4 * 4 = 16.
