Question

What Is the formula to find perimeter

Answer 1

Answer:

It depends on the shape you're finding the perimeter of.

Step-by-step explanation:

Each shape has a different formula to find their perimeter, which can be broken down like so:

Perimeter of a Triangle: a + b + c

Perimeter of a Square: 4 * x (x means length of side)

Perimeter of a Rectangle: 2 x (w + h) (w = width; h = height)

Perimeter of a Circle: 2πr (r = radius)

And so on.

Answer 2

The formula for the perimeter of a rectangle is often written as P = 2l + 2w, where l is the length of the rectangle and w is the width of the rectangle. The area of a two-dimensional figure describes the amount of surface the shape covers. You measure area in square units of a fixed size.
