Tips

  • 1 m² ≈ 10.76 ft².
  • Multiply length × width in metres to get m².
  • For a mental image: a square tile 1 m × 1 m covers 1 m².

Common mistakes

  • Writing m2 or m^2 in formal documents — the correct notation is m².
  • Confusing m² with m — one is area, the other length.
  • Treating 2 m² as twice 1 m² in side length — it is actually √2 × 1 m on each side.
