Source the Perimeter Formula you require Quickly and Efficiently

Perimeter Formula Lists are few and far between on the internet. Sometimes you just want the area formula for a number of different shapes.  And that is what I offer you here.  So no more hopping around from one page to another - they are all here for you.

I also have a similar page offering:

Area Formula

Surface Area Formula  and

 Volume Formulas





However, should you want a number of different formula for one particular shape - then please visit our geometry formula page, where you will find an alphabetical listing of all the shapes the elementary math student studies.
