Perimeter

The perimeter is a mathematical term that refers to the total distance around the outside of a geometric shape

The perimeter is a mathematical term that refers to the total distance around the outside of a geometric shape. It is calculated by adding up the lengths of all the sides of a shape.

In the case of two-dimensional shapes, such as rectangles, squares, or triangles, the perimeter is simply the sum of the lengths of the sides. For example, if you have a rectangle with lengths of 4 units and 6 units, the perimeter would be 4 + 4 + 6 + 6 = 20 units.

For more complex shapes, such as polygons, the perimeter is calculated by adding up the lengths of all the sides. This can be done by breaking down the shape into smaller, simpler shapes and calculating their individual perimeters. Once you have the individual perimeters, you can add them together to find the total perimeter of the shape.

It’s important to note that perimeter is a measure of distance, so it is always expressed in units, such as inches, centimeters, or meters, depending on the system of measurement being used.

Understanding the concept of perimeter is valuable in various real-life scenarios, such as measuring the distance around a garden, designing fences, or determining the amount of material needed for the edges of a fabric or flooring.
