Perimétert

Perimétert is a term used in geometry to describe the total distance around the boundary of a two-dimensional shape. It is essentially the length of the outline of a figure. For simple shapes like squares and rectangles, the perimeter can be calculated by adding the lengths of all its sides. For a rectangle with length L and width W, the perimeter is 2L + 2W. For a square with side length S, the perimeter is 4S.

Calculating the perimeter of more complex or irregular shapes may require more advanced mathematical techniques. For curved shapes, such as circles, the perimeter is called the circumference. The circumference of a circle with radius r is given by the formula 2πr, where π (pi) is a mathematical constant approximately equal to 3.14159. The concept of perimeter is fundamental in various applications, including land measurement, construction, and design, where determining the extent of a boundary is crucial. Understanding perimeter allows for the quantification of the outer limits of a shape.
