%e For n=3, we have the triangle with sides 3, 4 and 5. Its area is 6.

%e For n=4, we have the quadrilateral with sides 10, 17, 28, 35, diagonals 21 and 39, and area 378.

%e For n=5, we have the 5-gon with sides 21, 41, 175, 140, 85, diagonals 50, 105, 104, 204, 195, and area 9870.

%e For n=6, we have the 6-gon with sides 47, 663, 264, 169, 105, 1020, diagonals 700, 884, 975, 855, 952, 1001, 425, 520, 272, and area 196950.

%e For n=7, we have the 7-gon with sides 235, 1320, 1360, 2340, 612, 525, 5100, diagonals 1547, 2805, 4557, 4875, 2600, 4420, 4760, 5005, 3500, 3952, 4301, 2880, 3315, 1131, and area 5695998.

%e For n=8, we have the 8-gon with sides 1547, 612, 525, 5355, 235, 4275, 845, 1360, diagonals 2125, 2600, 5365, 5304, 2163, 1131, 5520, 5525, 3500, 2805, 5460, 5491, 3952, 3315, 5408, 4301, 3720, 4420, 4875, 4760, and area 12473070.
