Perimeter = 26.0000 m

  • The perimeter is 26.0000 m, meaning you would need 26.00 m of fencing or trim to go all the way around.
  • The area enclosed is 40.0000 m².
  • The diagonal distance from corner to corner is 9.4340 m, useful for checking that a frame is square.
  • The area-to-perimeter ratio is 1.538 m - a square of the same perimeter would have a slightly larger area.

Next stepNeed to tile, carpet, or fence the space? Use the area figure for material quantity and the perimeter for the edging or border length.
