The formula for the perimeter of a two-dimensional shape depends on the type of shape. For example:

- The perimeter of a rectangle is given by the formula: P = 2l + 2w, where P is the perimeter, l is the length, and w is the width.
- The perimeter of a square is given by the formula: P = 4s, where P is the perimeter and s is the length of one side.
- The perimeter of a triangle is given by the formula: P = a + b + c, where P is the perimeter and a, b, and c are the lengths of the sides.

By using these formulas, you can calculate the perimeter of a shape given its dimensions. For example, if you know the length and width of a rectangle, you can use the formula P = 2l + 2w to find its perimeter. If you know the length of one side of a square, you can use the formula P = 4s to find its perimeter. If you know the lengths of the sides of a triangle, you can use the formula P = a + b + c to find its perimeter.
