Calculating the Perimeter of a Rectangle. The perimeter of a rectangle is the distance around the outside of the rectangle. A rectangle has four sides with opposite sides being congruent. The formula for finding the perimeter is Side A + Side B + Side A + Side B. This could also be stated as 2*Side A + 2*Side B or 2*(Side A + Side B) Return to Top.
Metes and bounds. Metes and bounds is a system or method of describing land, real property (in contrast to personal property) or real estate. The system has been used in England for many centuries, and is still used there in the definition of general boundaries.
Geometric dimensioning and tolerancing. Geometric Dimensioning and Tolerancing (GD&T) is a system for defining and communicating engineering tolerances. It uses a symbolic language on engineering drawings and computer-generated three-dimensional solid models that explicitly describes nominal geometry and its allowable variation.
