Quizplus · Accepted Answer

To find the total area of the lawn, we use the formula: 
Area = length × width
Area = 160 feet × 120 feet
Area = 19200 square feet
To cover this area, we need to purchase:
Number of bags = Total area ÷ Area covered by one bag
Number of bags = 19200 ÷ 2000
Number of bags = 9.6
Since we cannot purchase a fraction of a bag, we need to round up to the nearest whole number. Therefore, we need to purchase 10 bags of fertilizer. The area of the rectangular lawn is 160 * 120 = 19,200 square feet.
To cover this area, we need 19,200 / 200 = 96 bags of fertilizer.
Therefore, the answer is choice B, 10 bags (rounded up from 9.6).
