For an industrial structure with a perimeter of 1000 feet by 100 feet and a requirement for 2-foot wide strips, how much Active Ingredient will be used if mixed according to label instructions?

To determine the correct amount of Active Ingredient (AI) needed for the industrial structure, it’s essential first to calculate the area that requires treatment. The perimeter of the structure measures 1000 feet by 100 feet, which gives a total perimeter of 2000 feet since it's a rectangle.

Given that the requirement involves applying a 2-foot wide strip around the perimeter, the treated area can be calculated. The total perimeter (2000 feet) multiplied by the width of the strip (2 feet) will yield the area to be treated:

Area = Perimeter × Width = 2000 feet × 2 feet = 4000 square feet.

Once the area is established, it's necessary to refer to label instructions for mixing ratios. These typically indicate how much Active Ingredient is used per square foot or per gallon of water. In this case, the correct choice indicates a mixture that aligns with established label instructions appropriately tailored for the area being treated.

The calculated amount for this treatment results in using 2.2 ounces of active ingredient combined with 4.4 gallons of water, as specified in this choice. This preparation ensures that the application rate conforms to the treatment guidelines while effectively addressing pest control needs without overuse of the chemical.
