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 (GD&T) is a system for defining and communicating engineering tolerances.D&T is used to define the nominal (theoretically perfect) geometry of parts and assemblies, to define the allowable variation in form and possible size of individual features, and to define the allowable variation between features. 1  Dimensioning specifications define the nominal, as-modeled or as-intended geometry. 2  Tolerancing specifications ...
