Area of figures
The area of a figure is the total numerical characteristic of all unit square elements of a plane. Depending on the size of the figures, the sides of the unit element square can be equal to 1 mm, cm, m, inch, km, etc. S figures can be measured in the following units: mm², cm², m², hectares, square kilometers, etc.

The area of a complex-shaped figure can be composed of various elementary figures: triangles, squares, rectangles, etc. The total area will be calculated by summing the areas of the component parts.
The set of online calculators on the page allows for quick calculations not only S flat figures (square, rectangle, circle, rhombus, ellipse), but also the areas of volumetric figures (cube, prism, cone, cylinder, sphere, tetrahedron, etc.), which are a combination of several planes.
Calculating areas of figures is in demand for solving various tasks:
- construction;
- cadastral;
- engineering, etc.
The state carries out cadastral accounting of land plots, the main parameter of which is the area. BTI specialists record the total and usable living area of apartments. In everyday life, it is sometimes necessary to calculate the area of a carpet, stretch ceiling, summer house plot, etc.
