Question 941522
Area = (side)*(side)


{{{A = s^2}}}


{{{72 = s^2}}} Plug in the given area. Now solve for 's'


{{{s^2 = 72}}}


{{{s = sqrt(72)}}} Apply the square root to both sides to get rid of the exponent of 2


{{{s = sqrt(36*2)}}}


{{{s = sqrt(36)*sqrt(2)}}}


{{{s = 6*sqrt(2)}}}


So the exact simplified side length is {{{6*sqrt(2)}}} inches
