The formula is 1/2 (apothem) (perimeter)
The perimeter of a dodecagon is the sum of the lengths of its 12 sides. These sides may be of different lengths.
L2 + H2 = P
The boundary or perimeter of a circle is called the circumference. The formula for calculating the length of the circumference is C = 2πr.
The perimeter of a circle is called its circumference. The formula for calculating the circumference is: C = πd (pi x diameter).In this case, this would be 8 in. x 3.14... or about 25.13 inches.

Assuming the shape is a regular dodecagon, with 12 angles and lengths the same, a dodecagon with sides of 9.25 centimetres has a perimeter of 9.25 x 12 = 110 centimetres.
There is no formula for a rectangle. There are formula for calculating its area, perimeter or length of diagonals from its sides, or it is possible to calculate the length of one pair of sides given the other sides and the area or perimeter, or the two lots of sides given area and perimeter and so on.

The formula to find the area of a dodecagon (12-sided polygon) is (apothem x perimeter)/2.
7 X 12 = 84 this is the perimeter
The boundary or perimeter of a circle is called the circumference. The formula for calculating the length of the circumference is C = 2πr.
