Question 136003
The area of a square is given by {{{A=s^2}}} where s is the length of one of the sides.  Doesn't matter which side because in a square they are all the same.


Since you are given the area as {{{14,400in^2}}}, you need to write the formula like this:


{{{s^2=14400}}}


Now all you have to do is take the square root of both sides


{{{sqrt(s^2)=s=sqrt(14400)}}}.


Just use your calculator.
