Let the width = $\"+w+\"$
\n" ); document.write( "The length is $\"+w+%2B+15+\"$
\n" ); document.write( "The formula for perimeter is:
\n" ); document.write( " $\"+P+=+2w+%2B+2%2A%28+w+%2B+15+%29+\"$
\n" ); document.write( " $\"+P+=+90+\"$
\n" ); document.write( " $\"+90+=+2w+%2B+2w+%2B+30+\"$
\n" ); document.write( " $\"+4w+=+90+-+30+\"$
\n" ); document.write( " $\"+4w+=+60+\"$
\n" ); document.write( " $\"+w+=+15+\"$
\n" ); document.write( " $\"+w+%2B+15+=+30+\"$
\n" ); document.write( "The dimensions are 15' x 30'
\n" ); document.write( "check:
\n" ); document.write( " $\"+P+=+2w+%2B+2%2A%28+w+%2B+15+%29+\"$
\n" ); document.write( " $\"+P+=+2%2A15+%2B+2%2A%28+15+%2B+15+%29+\"$
\n" ); document.write( " $\"+P+=+30+%2B+60+\"$
\n" ); document.write( " $\"+P+=+90+\"$
\n" ); document.write( "OK \n" ); document.write( "

\n" );
