To calculate the strip area in square feet, which operation uses swath width and a fixed distance?

• A. Multiply swath width by 200 ft.
• B. Multiply swath width by 100 ft
• C. Divide swath width by 200
• D. Add swath width to 200

Answer: (A)

Calculating strip area uses the rectangle area idea: area equals length times width. Here the swath width is the width, and the fixed distance is the length along which you’re measuring. Since that distance is 200 ft, you multiply the swath width by 200 ft to get the area in square feet. The units line up because feet times feet gives square feet. For example, if the swath width is 8 ft, the area would be 8 ft × 200 ft = 1600 ft².

Dividing the swath width by 200 would not yield an area, as it changes the operation and units. Adding the swath width to 200 would also not produce an area, since addition leaves units in feet, not square feet. Multiplying by a different fixed distance (like 100 ft) would give the area for a different length, which isn’t what’s specified here.
