The document defines and provides formulas for perimeter, area, and volume. It states that perimeter is the distance around a plane figure and provides an example calculation of 12 units. Area is defined as the space that covers a plane figure, and an example calculation of 9 square units is given using the length times width formula. Volume is defined as the space that fills a solid figure, and an example calculation of 24 cubic units is provided using the length times width times height formula.
