In method 2 calibration, what is the width required to spray 1 acre?

• A. 66 ft
• B. 43,560 ft
• C. 132 ft
• D. 528 ft

Answer: (A)

In method 2 calibration, the sprayed area is found by multiplying the swath width by the distance you travel: area = width × length. Since one acre equals 43,560 square feet, you can choose a travel length and solve for the needed width. If you travel 660 feet to cover one acre, the required swath width is 43,560 ÷ 660 = 66 feet. So the width you need is 66 feet to spray one acre in that calibration setup.

The other options don’t fit because 43,560 is the area in square feet, not a width; 132 feet would pair with a shorter travel distance (about 330 feet) to equal one acre; 528 feet would pair with a width of about 82.5 feet.
