Question

Quizplus · Accepted Answer

a) Area = 234.7 ft x 81 ft = 19,010.7 sq ft
b) Amount of insecticide required = 0.08 oz/sq ft x 19,010.7 sq ft ≈ 1520.856 oz, rounded to the nearest thousandth.

Therefore, option C is the correct choice. a) The area of the lawn is found by multiplying the length by the width: 234.7 ft × 81 ft = 19,010.7 sq ft.
b) To find the amount of insecticide required, we need to multiply the area of the lawn by the amount of insecticide per square foot: 19,010.7 sq ft × 0.08 oz/sq ft = 1520.856 oz. Rounding to the nearest thousandth gives 1520.857 oz, which should be rounded again to 1520.856 oz. Therefore, Nick needs to purchase 1520.856 oz of insecticide. The correct answer is C.
