Question: 144
2. The perimeter of Rectangle X is 40 m2. The area of Rectangle Y is 48 m2.
- A. The quantity in Column A is greater.
- B. The quantity in Column B is greater.
- C. The two quantities are equal.
- D. The relationship cannot be determined from the information given.
Correct Answer: A
Explanation:
The answer is A
First, write an equation to solve for p: p + p + 3p + 3p = 40. Combine like terms and divide by 8: p = 5. Now write an equation for q: q × 3q = 48. Combine like terms and divide by 3: q2 = 16. Take the square root of both sides: q = 4.
