See a solution process below:

Explanation:

The formula for the area of a square is:

#A = s^2#

Substituting #64"cm"^2# for #A# we can solve for #s# giving:

#64"cm"^2 = s^2#

#sqrt(64"cm"^2) = sqrt(s^2)#

#8"cm" = s#

The formula for the perimeter of a square is:

#p = 4s#

Substituting #8"cm"# from the calculation above for #s# and calculating #p# gives:

#p = 4 xx 8"cm"#

#p = 32"cm"#
