We've seen how to multiply a two digit number by another two digit number. Now we are going to apply that to area.

\text{Area of a rectangle } = \text{length } \times \text{width }

So if we had a length of 18 and a width of 42 we would get an equation that looks like this.

\text{Area } = 18 \times 42

Rather than trying to add up forty two 18s in our head, it is much simpler to break the area up into smaller parts, multiply them separately and then add them all together to get the total area.
