How do you calculate the square footage of a rectangular site?

To calculate the square footage of a rectangular site, you multiply the length by the width. This calculation is based on the geometric principle where the area of a rectangle is defined as the product of its two sides. By performing this multiplication, you obtain the total area represented in square units, which is essential for various applications, including landscaping, property assessments, and pest control measures.

Understanding this concept is particularly important, as knowing the area allows for more accurate application of aquatic pest control products, ensuring effective coverage and safety compliance. The other methods listed do not provide a measurement of area and therefore do not yield useful information for determining the square footage of a site.
