  "description": "A half-acre lot (21,780 square feet) fenced on all sides assuming a square shape needs roughly 590 linear feet of perimeter fencing. This calculator defaults to that estimate and computes total posts and cost based on your fence style and post spacing, fully editable for an actual perimeter measurement.",
  "formula": "Perimeter (square lot) = 4 × √(Area). Posts = Perimeter ÷ Post Spacing + 1. Cost = Perimeter × Price per Foot + Posts × Post Price.",

      "q": "How many linear feet of fence for a half acre?",

    {
      "q": "Does terrain affect the fence cost?",
      "a": "Yes, sloped or rocky terrain increases labor cost for post-hole digging significantly; the material cost here doesn't include difficult-terrain labor premiums."

      "q": "Is chain link or wood cheaper per foot for a half-acre lot?",
      "a": "Chain link is typically cheaper per linear foot than wood privacy fencing; adjust the price-per-foot field to compare styles side by side for your total lot perimeter."
