Math Help: Perimeter of squares, rectangles and triangles

Refresh your competency in the various areas of Mathematics.


In this module, you can study the meaning of "perimeter" and how to find the perimeter of a square, rectangle or triangle.


Did you know?

The perimeter of a rectangle is NOT the length times the width. (That's the area, not the perimeter.)

You do not find perimeter by counting squares around the outside of the shape.
