L2 + H2 = P
Area of regular polygon: 0.5*apothem*perimeter
Assuming the shape is a regular dodecagon, the formula for calculating the perimeter for a dodecagon of side length n is equal to 12n.
The formula is 1/2 (apothem) (perimeter)
The formula used to find the area of any regular polygon is A = 1/2 a P where the lower case a stands for the length of the apothem and the uppercase P stands for the perimeter of the polygon.
A = (1/2)Pa A being the area, P being the perimeter of the regular polygon, and the apothem length being a.

Assuming the shape is a regular dodecagon, the formula for calculating the perimeter for a dodecagon of side length n is equal to 12n.
The formula is 1/2 (apothem) (perimeter)
The formula used to find the area of any regular polygon is A = 1/2 a P where the lower case a stands for the length of the apothem and the uppercase P stands for the perimeter of the polygon.
The side of the Polygon's measurements multiplied by 5.
A = (1/2)Pa A being the area, P being the perimeter of the regular polygon, and the apothem length being a.
There can be no such formula in general. A formula will exist if the area is a regular polygon (or a circle).
The formula is:Perimeter = (length of one side) x (number of sides)
Multiple of total no of sides and length of each side.
The answer depends on what information you have about the regular polygon. You need to know, or be able to derive, the number of sides (n) and the length of each side (L). Then the perimeter is n*L units of length.
The general formula isPerimeter = (sum of the lengths of all sides)In the special case of a regular polygon,Perimeter = (length of one side) x (number of sides)
If the polygon has n sides, then the perimeter is 2.75*n metres.
