a=b 2 sides of the square.
\n" ); document.write( "c=the diagonal.
\n" ); document.write( "a^2+b^2=c^2
\n" ); document.write( "a^2+a^2=c^2
\n" ); document.write( "2a^2=12^2
\n" ); document.write( "2a^2=144
\n" ); document.write( "a^2=144/2
\n" ); document.write( "a^2=72
\n" ); document.write( "a=sqrt72
\n" ); document.write( "a=8.5 in. ans. for one side.
\n" ); document.write( "4*8.5=36 in for the perimeter.
