Answer :

  • AC = 12√2
  • BC = 12
  • DE = 6√2
  • DC = 12

Explanation :

The diagonals of a square are equal in nature, moreover they bisect each other.

thus,

  • AC = 2*EC
  • AC = 2*6√2
  • AC = 12√2

also,

  • AC = DB
  • AE + EC= DE + EB
  • EC + EC = DE + DE
  • 2EC = 2DE
  • EC = DE
  • DE = 6√2

The side of a square is given by,

  • s = d/√2
  • BC = AC/√2
  • BC = 12√2/√2
  • BC = 12

since all the sides of a square are equal therefore,

  • DC = 12
