Perimeter of figures

The perimeter of figures is the length of their boundary lines. Knowing the perimeter is required in various practical situations. The perimeter of figures is closely related to determining their area.

There is no general formula for calculating the perimeters of various figures, and for this reason, the page offers a set of online calculators that allow you to calculate this parameter for basic geometric figures. There are programs for calculating the lengths of a circle and an arc.

Using the calculators is very easy, you need to set the coordinates of the figure's points, the values of the side lengths, radii, or angles in the appropriate fields. When you press the button«Calculate» in the corresponding field you can read the result.

Software scripts use the following perimeter calculation formulas:

- P = 2 x π x r;
- P = a + b +c;
- P = 4 x a;
- P = 2 x (a + b);
- P = a + b + c + d;
- P = n x a
and others.

In everyday life, the calculation of the perimeter is most often necessary to determine the amount of building materials for the construction of a fence for a residential or industrial site, a parking area, a grazing area, etc.
