Description of formula: In the formula, A and B are the sides of parallelogram, and C is the perimeter of parallelogram.

Definition: The perimeter of a parallelogram is the sum of the sides of the parallelogram.

Extended data:

Circumference:

The length integral of the edge around a finite area is called the perimeter, which is the length of a graph.

Formula:

Circle: C=πd=2πr (d is diameter, r is radius, π).

The circumference of a triangle is C = a+b+c(abc is three sides of a triangle).

Quadrilateral: C=a+b+c+d(abcd is the side length of quadrilateral)

Special: rectangle: C=2(a+b) (a length b width)

Square: C=4a(a is the side length of the square)?

Polygon: C= sum of all sides.

Sector circumference: C = 2R+nπR÷ 180? (n= central angle) = 2R+kR (k= radian)
