You cannot. The perimeter alone does not provide enough information unless the octagon is regular and there is no valid reason to assume that it is.

perimeter = 4 x sqrt 72 = 33.94 in area = 72 squinches
If the perimeter of the hexagon is 72, then each side of the hexagon is 72/6 = 12. Therefore, one side of the square is also 12, since the hexagon and the square share a side, so the area of the square is 12 x 12 = 144 cm.
Area of square: 324 square inches Perimeter of square: 72 inches

The perimeter is 72.
72 units (9 x 8 = 72)
It is 72 cm/8 = 9 cm.
The area of a regular octagon: A = (2 x apothem)2- (length of side)2 or in this case A= (2 x 8.45)2 - 72
-7
72 because if the area is 324 and you make a block chart and count the sides it will equal 72
perimeter = 4 x sqrt 72 = 33.94 in area = 72 squinches
72cm (9mm x 8 sides = 9 x 8 = 72)
The area is 324 square units.
