To find the area of a rectangle, you need to multiply the length by the width. Here are the steps:
1. Find the length of the rectangle. In most cases, you will be given the length, but if not, you can find it using a ruler.
2. Find the width of the rectangle. Use the same methods to find it.
3. Write the length and width next to each other.
4. Multiply the length times the width.
5. State your answer in square units.
For example, if you have a rectangle with a length of 5 cm and a width of 3 cm, you would multiply 5 by 3 to get an area of 15 square centimeters.
