When making a broadcast application of a granular pesticide, what is the application rate per acre if 3 pounds are spread over 20' x 50'?

To determine the application rate per acre when spreading 3 pounds of a granular pesticide over an area of 20 feet by 50 feet, it is essential to first calculate the area that is being treated. The area can be calculated by multiplying the length by the width:

Area = 20 feet * 50 feet = 1000 square feet.

Next, we need to convert the area from square feet to acres. One acre is equivalent to 43,560 square feet. Thus, to find the area in acres, we divide the 1000 square feet by the number of square feet in an acre:

Area in acres = 1000 square feet / 43,560 square feet per acre = approximately 0.023 acres.

Now, we take the amount of pesticide applied (3 pounds) and determine the application rate per acre by dividing the total pounds of pesticide by the area in acres:

Application Rate = 3 pounds / 0.023 acres ≈ 130.43 pounds per acre.

When rounding to the nearest whole number, this gives us an application rate of approximately 131 pounds per acre.

This answer represents the correct application rate for the broadcast application of the pesticide based on the specified area. Understanding these calculations
