Let the width = $\"+x+\"$

\n" ); document.write( " $\"+2%2Ax+%2B+2%2A%283x%29+=+24+\"$
\n" ); document.write( " $\"+2x+%2B+6x+=+24+\"$
\n" ); document.write( " $\"+8x+=+24+\"$
\n" ); document.write( " $\"+x+=+3+\"$
\n" ); document.write( "and
\n" ); document.write( " $\"+3x+=+9+\"$
\n" ); document.write( "------------------
\n" ); document.write( "Area = $\"+3%2A9+=+27+\"$ cm2
\n" ); document.write( "---------------------------------
