In this publication, we will consider what the perimeter of a geometric figure is, how it is considered, and also analyze examples to demonstrate the practical application of theoretical knowledge.
Perimeter definition
Perimeter – this is the sum of the lengths of all sides of a geometric figure (triangle, square, trapezoid, rhombus, etc.).
To measure the perimeter, units of length are used: millimeters (mm), centimeters (cm), meters (m), kilometers (km), etc.
The generally accepted designation of the perimeter is the Latin letter “P“, under which you can add the abbreviated name of the figure or its symbol. For example:
- The perimeter of a triangle can be written as “Ptreug.“ or “P△“;
- The perimeter of the square is “Pquad.“ or “P□“
