If one gallon of pesticide covers 43,560 square feet, how many gallons are needed to treat an area of 3 acres?

To determine the number of gallons needed to treat an area of 3 acres, it's essential to first convert acres into square feet, since the coverage of the pesticide is given in square feet. One acre is equivalent to 43,560 square feet. Therefore, to find the total area in square feet for 3 acres, you would multiply the number of acres by the square feet per acre:

3 acres × 43,560 square feet/acre = 130,680 square feet.

Next, with the pesticide's coverage specified as 1 gallon covering 43,560 square feet, you can calculate how many gallons are necessary to cover 130,680 square feet. To find this, divide the total square footage that needs treatment by the coverage per gallon:

130,680 square feet ÷ 43,560 square feet/gallon = 3 gallons.

This result indicates that 3 gallons are required to completely treat the 3 acres.

In this scenario, the closest answer choice to the calculated requirement of 3 gallons is 5 gallons. The answer indicated as 2 gallons would not provide adequate coverage for the entire area, while 7 gallons and 9 gallons exceed the necessary amount, making them less desirable options. Therefore, the
