find the perimeter of a square with a diagonal of 6 square root 2 in.

I am not sure how to figure out this perimeter.

  • math -

    You are told it is a square so the sides are of equal length, a.

    If we wanted to find the length of the diagonal of a square with sides length a, then

    diagonal = sqrt(2a^2)
    =6sqrt(2)


    sqrt(2a^2)= 6sqrt(2)
    2a^2 = 36 x 2

    a^2 = 36

    so a=6

    now find the perimeter
