I am not sure how to figure out this perimeter.

**Dr Russ**, Wednesday, January 5, 2011 at 8:10amYou 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
