Definition: In math, the perimeter of a shape is the total distance around the outer boundary of the shape. Another way to describe the perimeter of a figure is the total measured length of the outline of the shape. Note that perimeter applies to two-dimensional shapes including triangles, rectangles, squares, etc.
