The perimeter of a geometric shape is the total length of all its sides. Understanding the perimeter is essential in geometry, as it helps in various real-world applications. In this article, we will explore the concept of perimeter, its formula, and its applications.

Perimeter Formula

The formula to calculate the perimeter of different shapes varies. Here are some common shapes and their respective perimeter formulas:

  • Square: (P = 4 \times \text{side length})
  • Rectangle: (P = 2 \times (\text{length} + \text{width}))
  • Circle: (P = 2 \times \pi \times \text{radius})
  • Triangle: (P = a + b + c) (where (a, b,) and (c) are the lengths of the three sides)

Applications

The concept of perimeter is widely used in various fields:

  • Architecture: Determining the perimeter of a building helps in calculating the required materials and labor.
  • Civil Engineering: The perimeter is crucial in planning roads, buildings, and other infrastructure projects.
  • Real Estate: The perimeter of a property is an important factor in determining its value.

Example

Let's say you have a rectangular garden with a length of 10 meters and a width of 5 meters. The perimeter of the garden would be:

[P = 2 \times (10 + 5) = 30 \text{ meters}]
