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)
