A certain park has an area of 11,863,808 square yards. What is the area, in square miles, of this park?(1 mile = 1,760 yards)
Correct answer: B. 3.83
- A. 1.96
- B. 3.83
- C. 3,444.39
- D. 6,740.8
Explanation
Choice B is correct. To convert the area from square yards to square miles, we need to understand that 1 mile is equal to 1,760 yards. Therefore, 1 square mile is equal to 1,7602 = 3,097,600 square yards. Given the park's area of 11,863,808 square yards, we divide this by 3,097,600 square yards per square mile to find the area in square miles: 11,863,808 ÷ 3,097,600 = 3.83 square miles.Choice A results from a miscalculation, Choice C is the square root of the area in square yards, and Choice D involves incorrect conversion from yards to miles without squaring.
