Obwodzie
Obwodzie is the Polish term associated with geometry that denotes the perimeter or boundary length of a two-dimensional figure. The base noun is obwód (perimeter, circumference); obwodzie is one of its grammatical forms (locative and vocative) used in phrases such as "na obwodzie koła" (on the circumference of a circle) or "w obwodzie prostokąta" (in the perimeter of a rectangle). In mathematics, obwód refers to the total length of a figure's boundary.
For common shapes, formulas are used to compute the obwód: for a circle with radius r, obwód
Perimeter is distinct from area but related. The isoperimetric principle states that among figures with a given
In educational contexts, obwód is introduced alongside area (pole) in geometry curricula, with problem types including
