William Blackwell  
Perimeter Efficiency, also known as Isoperimetric Inequalities, compares the actual perimeter of a shape with the circumference of the circle that would be required to enclose the same area. Since a circle will enclose any given area with the least amount of perimeter, it is said to be 100 percent efficient as an area enclosure. Pages include information about perimeter efficiency, and practical uses, with text, formulas, tables, and drawings.
