Let width be W
\n" );
document.write( "Then length is: 6W + 10 
\n" );
document.write( "Area (viewable) is 7,700 m, so we get: W(6W + 10) = 7700
\n" );
document.write( "
\n" );
document.write( "
\n" );
document.write( " ------ Factoring out GCF, 2

document.write( "
\n" );
document.write( "(W - 35)(3W + 110) = 0
\n" );
document.write( "W, or width =  m        OR           (ignore)
\n" );
document.write( "Length: 6(35) + 10, or 210 + 10, or  m \n" );
document.write( "

\n" );
