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