Perimeeter

Perimeeter is a term used in geometry to describe the total distance around the outside of a two-dimensional shape. It is essentially the length of the boundary of a figure. For simple shapes like squares and rectangles, the perimeeter can be calculated by adding the lengths of all its sides. For example, a square with sides of length 5 units would have a perimeeter of 5 + 5 + 5 + 5 = 20 units. A rectangle with a length of 10 units and a width of 4 units would have a perimeeter of 10 + 4 + 10 + 4 = 28 units.

The concept of perimeeter is also applicable to more complex polygons, where one simply sums the lengths of all their constituent sides. For curved shapes, such as circles, the perimeeter is known as the circumference. The formula for the circumference of a circle is 2πr, where 'r' represents the radius of the circle and 'π' (pi) is a mathematical constant approximately equal to 3.14159. Understanding perimeeter is a fundamental concept in geometry and has practical applications in various fields, including construction, design, and everyday measurement tasks. It provides a way to quantify the extent of a surface's edge.
