Area of a rectangle is $\"Area+=+Length+%2A+Width\"$
\n" ); document.write( " $\"Area+=+%282x-1%29+%2A+%28x%2B2%29\"$
\n" ); document.write( " $\"Area+=+2x%2A%28x%2B2%29+-1%2A%28x%2B2%29\"$
\n" ); document.write( " $\"Area+=+2x%5E2+%2B+4x+-+x+-+2\"$
\n" ); document.write( " $\"Area+=+2x%5E2+%2B+3x+-+2\"$ \n" ); document.write( "
