# Study Tips

Tip #1
A rectangle has four right angles. The sides of a rectangle that are opposite each other have the same length.

Note that, the longer side of a rectangle is the length and the shorter side is the width. Also, a square is a special type of rectangle.

Now, for a rectangle with length l and width w,  its area, A will be:
A = lw

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