how do you find the perimeter?

Answer 1

To find the perimeter of a shape, you need to add up the lengths of all its sides. The formula to find the perimeter may vary depending on the shape.

For a rectangle or a square:
- Perimeter = 2 × (Length + Width)

For a triangle:
- Perimeter = Side1 + Side2 + Side3

For a regular polygon (having equal sides):
- Perimeter = Number of sides × Length of one side

For a circle:
- Perimeter (also called the circumference) = 2 × π × Radius

These are the basic formulas for finding the perimeter of common shapes. Keep in mind that there might be additional formulas for specific irregular shapes.
