Perimeter
Perimeter is the distance around the outside of a figure.
The perimeter of a rectangle is derived by adding all four sides. Since the two lengths are equal, and the two widths are equal, then it can be written as P = 2l + 2w.
For squares, the perimeter is found the same way (add all 4 sides). Since all sides are the same, however, you can use the formula P = 4s.

P = 2w + 2lP = 2(5) + 2(18)P = 10 + 36P = 46 cm
Perimeter results in regular units, not square units.
