since this is an isosceles the two sides are equal

\n" ); document.write( " $\"x%5E2%2Bx%5E2=3%5E2\"$
\n" ); document.write( ":
\n" ); document.write( " $\"2x%5E2=9\"$
\n" ); document.write( ":
\n" ); document.write( " $\"x%5E2=9%2F2\"$
\n" ); document.write( ":
\n" ); document.write( " $\"x=3sqrt%282%29%2F2\"$
\n" ); document.write( ":
\n" ); document.write( "perimeter is $\"3sqrt%282%29%2B3sqrt%282%29%2B3\"$
