How To Square Up a Concrete Slab or Structure

[@The_Aussie_Enquirer]

For those that don’t have a construction calculator it’s just Pythagoras theorem. A squared plus B squared= C squared… Square the 20 ft( I.e 20 x 20) = 400 and then square the 30ft ( 30 x 30) =900 then add the answers together I.e 400 plus 900 =1300 and then run the square root of 1300 which equals 36.055 ft or 36 11/16.. Sorry, I’m in Australia so it’s easy for us we just use millimetres so it’s super simple. I’m not 100 % sure if this is just as easy with fractions of inches that your tapes measure 😬

@The_Aussie_Enquirer yes exactly. This is to show how you use the equation in a real life scenario......by starting with two parallel lines.
