add all the sides together or if it has two sides the same number, multiply the number by the number of numbers. Also if the shape is not a regular shape break it apart into a shape you know and when you are done add all the perimeters of the shapes you broke apart together. The formula is length times width. Are you a grownup????!!!!! 'Cause that would be WEIRD
