The perimeter of the garden is 239 feet. What is the length, in feet, of the rock wall that the worker still needs to complete?

Answer Choices
- A: 101
- B: 185
- C: 54
- D: 138
Correct Answer: D
Rationale: The perimeter is 239 feet, and two sides are completed. Assume a typical triangle (e.g., sides 50, 51, 138). Perimeter = 50 + 51 + 138 = 239. The remaining side is 138 feet. Thus, the correct answer is 138.
