You can put this solution on YOUR website!
$\"x\"$ = length of the side, in feet
\n" ); document.write( " $\"area=x%2Ax=x%5E2=324\"$
\n" ); document.write( " $\"x=sqrt%28324%29=18\"$
\n" ); document.write( "So the side measures $\"highlight%2818feet%29\"$
\n" ); document.write( "How do you find the square root?
\n" ); document.write( "There are many ways.
\n" ); document.write( "1)You can use a calculator that has a square root key.
\n" ); document.write( "2)You can try different numbers:
\n" ); document.write( " $\"20%2A20=20%5E2=400\"$ and $\"324\"$ is less that that, so you know that $\"x\"$ is less than $\"20\"$ .
\n" ); document.write( " $\"15%2A15=225\"$ and $\"324\"$ is more that that, so you know that $\"x\"$ is more than $\"15\"$ .
\n" ); document.write( " $\"17%2A17=289\"$ and $\"324\"$ is more that that, so you know that $\"x\"$ is more than $\"15\"$ .
\n" ); document.write( "If you then calculate $\"18%2A18\"$ you realize that $\"18%2A18=18%5E2=324\"$ so $\"18\"$ is the answer.
\n" ); document.write( "3)you could factor $\"324\"$
\n" ); document.write( " $\"324=2%2A162\"$ and $\"162=2%2A81%7D%7D+so+%7B%7B%7B324=2%2A2%2A81\"$
\n" ); document.write( "Since you know that $\"81=9%2A9\"$ $\"324=2%2A2%2A9%2A9=%282%2A9%29%2A%282%2A9%29=18%2A18=18%5E2\"$ \n" ); document.write( "

\n" );
