The perimeter of a heptagram can be calculated using the following formula: if you know the length of a side.
If you know the length of one of the sides of the heptagram, you can calculate its perimeter using the following formula:
$$"perimeter" = S * 14$$
$$14 = "number of sides in a heptagram"$$
$$S = "side"$$
It is a geometric figure with 14 sides and 7 vertices, all the sides have equal length. Also an heptagram has all the same angles. all regular heptagrams look the same.
An irregular heptagram can have vitually infinite posibles shapes, Despite this all have 17 sides and 7 vertices.
A perimeter is defined by the outer path of a shape. The shape is always in 2 dimensions. The perimeter is the total length of the exterior path. Another way of looking at this is to think of it as the boundary length of a shape.
In the case of a circle, the perimeter is called a circumference.
Perimeter has a Greek origin, "peri" means "around", and "meter" means "measure". So perimeter means "measure around".
It is a representation of a rule or a general principle using letters. (Algebra, A. Baldor)
When describing formulas in plural, it is also valid to say "formulae".
