## How To Find The Perimeter Of A Rectangle

Let's look at the geometric characteristics of a rectangle. But first, please review the definition of Perimeter Of Two-Dimensional Shapes, Angle and Right Angle.
• A rectangle has unique features, there are four sides; two side have the same length - let's call these two sides the Length (L).
• The other two sides have the same length but their length is different from the first lengths - let's call these two sides the Width (W).
• Another feature of a rectangle, at the end each Line Segment the next Line Segment is Perpendicular.
• Another feature of a rectangle, two sides are parallel. Also the other two sides are parallel and at right-angles to the first set of sides.
• Special note, both the height and base lengths of a rectangle must be greater than zero.

Perimeter Of A Rectangle Formula
Formula = Length + Width + Length + Width =
Formula = (2 × Length) + (2 × Width) =
Formula = 2 × (Length + Width) =
Formula = 2 × (L + W) Perimeter Of A Rectangle Calculator
