Tip #1

A rectangle has four right angles. The sides of a rectangle that are opposite
each other have the same length.

Now, if a rectangle has the length of**l** and the
width of **w**, its
perimeter,** P**, will be the total distance around the
outside of the rectangle. Hence:

**P** = **2(****l****+****w****)**

The math video below will give more explanation on this. Also, we will see some examples on how to use this formula.
