What is the the formula for perimeter?

Answer 1

P= w + w + L + L

OR:

P= 2w + 2L

* * * * *

The above is true only for parallelograms (or kites) but not for other quadrilaterals or other polygons. Triangles DO have a perimeter. And the shape need not even be a polygon - a semicircle has a perimeter.

So the correct answer is:

Perimeter = sum of all the sides of the figure.
Length plus width times two

Answer 2

2 x length + 2 x width

length + width x 2

Add the lengths of each side together.

On a four-sided figure (square or rectangle) this would be:

length + length + width + width, OR

2 x length PLUS 2 x width (2L + 2W)

Answer 3

Add up the distances of all the sides of the shape. It is like it is a fence and you add up how much fence you would need to go all the way around it.

Answer 4

Add together the lengths of all of the sides.
