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.
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)
2a^2 = 36 x 2
a^2 = 36
now find the perimeter
