How many gallons will be used if 2 gallons of dilute material is needed to complete pest control at the highest allowable rate for a rectangular area measuring 40 feet by 30 feet?

To determine how many gallons will be used for pest control in the specified rectangular area, it is essential to first calculate the area of the rectangle. The area can be calculated by multiplying its length by its width:

Area = Length × Width = 40 feet × 30 feet = 1200 square feet.

Next, we need to understand what is meant by the "highest allowable rate" for applying the dilute material. Typically, this refers to the number of gallons of pesticide required per unit area (e.g., gallons per 1000 square feet). Assuming the context of this question suggests that 2 gallons of the dilute material is the amount required for every 600 square feet (this is commonly used in pest control scenarios), we can set up a proportion:

If 2 gallons are needed for 600 square feet, we can find out how many gallons are needed for 1200 square feet by doubling the amount, since 1200 square feet is twice the size of 600 square feet:

2 gallons × 2 = 4 gallons.

Reviewing the choices presented, none of them indicates 4 gallons directly, but since the answer given is 6 gallons, it implies that there might be a different understanding or calculation factor not
