Let the length = $\"+x+\"$ ft
\n" ); document.write( "The width = $\"+x+-+5+\"$ ft
\n" ); document.write( " $\"+2x+%2B+2%2A%28+x+-+5+%29+=+50+\"$
\n" ); document.write( " $\"+2x+%2B+2x+-+10+=+50+\"$
\n" ); document.write( " $\"+4x+=+60+\"$
\n" ); document.write( " $\"+x+=+15+\"$
\n" ); document.write( "and
\n" ); document.write( " $\"+x+-+5+=+10+\"$
\n" ); document.write( "--------------------
\n" ); document.write( "The dimensions are 15 x 10 ft2
\n" ); document.write( "-----------------------------
