Answer:

See a solution process below:

Explanation:

The formula for the Area of a square is:

#A = s^2# Where #s# is the length of the side of the square.

Substituting and solving for #s# gives:

#64"units"^2 = s^2#

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

#8"units" = s#

The formula for the perimeter of a square is:

#p = 4s# Where #s# is the length of the side of the square.

Substituting the length for the side of the square in the problem we calculated above and solving for #p# gives:

#p = 4 xx 8"units"#

#p = 32"units"#

The perimeter of the square in the problem is 32 units.
