To calculate the area of a rectangle, multiply its length and width.
A=l* w
From the figure, we see that the width is 2 centimeters and the length is 3 centimeters, so we have enough information to calculate the rectangle's area.
The area of the given rectangle is 6 squared centimeters.

Formula for the Area
We know that the area is the number of square units needed to cover a surface. Since there are so many figures with different shapes, we can have a formula for the area of each figure. Let's see some examples!
Sometimes, we will come across with complex figures without a formula for the area. In that cases, we can follow the next steps.
Break the shape down into simpler figures.
Find the area of each smaller figure. We can use the known formulas for the area.
Add the areas of each smaller figure. The total area will be the area of the complex figure.
For those of you who are interested in learning more about the area of other figures, you can read more about them on the following pages.
