What is how to find perimeter?

The perimeter is the total distance around the outside of a two-dimensional shape. Here's how to find it:

• General Approach: Simply add up the lengths of all the sides of the shape. This works for any polygon.

• Specific Shapes:

  • Square: Since all four sides are equal, multiply the length of one side by 4. (<a href="https://www.wikiwhat.page/kavramlar/Square">Square</a>)
  • Rectangle: Add the length and width, and then multiply the result by 2. (Perimeter = 2 * (length + width)). (<a href="https://www.wikiwhat.page/kavramlar/Rectangle">Rectangle</a>)
  • Triangle: Add the lengths of all three sides. (<a href="https://www.wikiwhat.page/kavramlar/Triangle">Triangle</a>)
  • Circle: The perimeter of a circle is called the circumference. Calculate it using the formula: Circumference = 2 * π * radius (or π * diameter), where π (pi) is approximately 3.14159. (<a href="https://www.wikiwhat.page/kavramlar/Circle">Circle</a>)

• Units: Remember to include the units of measurement (e.g., cm, m, in, ft) in your answer. The perimeter will be in the same units as the sides of the shape.
