What is the formula for calculating the square footage of a rectangle?

The formula for calculating the square footage of a rectangle is based on the fundamental property that the area of a rectangle is the product of its length and width. By multiplying these two dimensions together, you obtain the total area within the rectangle, which is measured in square units, typically square feet for this context.

Length refers to the longer side of the rectangle, while width refers to the shorter side. This relationship remains constant regardless of the orientation of the rectangle; whether it is taller or wider, the area remains defined as the product of these two measurements. Utilizing this formula is crucial for various applications, such as flooring, painting, or any task that involves determining surface area.

While other options mention combinations of dimensions, they do not succinctly define the area of a rectangle specifically. The focus on length and width ensures clarity in calculating square footage, making it applicable for practical use in various real-world scenarios.
