How do you calculate the area of a rectangle.

area of a rectangle is length x width.

To calculate the area of a rectangle, you need to multiply its length by its width. Here's a step-by-step breakdown of how you can find the area of a rectangle:

1. Measure the length of one of the sides of the rectangle.
2. Measure the width of the rectangle, which is the side perpendicular to the length.
3. Multiply the length by the width.

For example, let's say the length of a rectangle is 5 units and the width is 3 units. To find the area, you would multiply the length (5) by the width (3), resulting in an area of 15 square units.

Formula: Area of a rectangle = Length × Width

Keep in mind that the answer will always be in square units since you are calculating the area.
