  "description": "A quarter-acre lot (10,890 square feet) fenced on all sides assuming a square shape needs about 417 linear feet of perimeter fencing. This calculator defaults to that assumption, then computes post count and total material cost based on your fence style price per foot and post spacing — adjust the perimeter directly if your lot isn't square.",
  "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 quarter acre?",
      "a": "Assuming a square lot, about 417 linear feet — a quarter acre is 10,890 square feet, and the side length of a square with that area is roughly 104 feet, times 4 sides."

      "q": "Does this account for gates?",
      "a": "No, add gate hardware and framing separately since gate cost varies widely by width and material; this tool covers straight-run fencing and posts only."

      "a": "Enter your actual perimeter directly in the first field — the 417 ft default only applies to a square lot; a long narrow rectangle of the same area has a longer perimeter."
