\n" );
document.write( "Hi,
\n" );
document.write( "Let x represent the width, then the length  would be (x+4)
\n" );
document.write( "Perimeter is the Sum of all sides
\n" );
document.write( "x + x + (x+4) + (x+4) = 20in
\n" );
document.write( "solving for x
\n" );
document.write( "4x + 8 = 20in
\n" );
document.write( "4x = 12in 
\n" );
document.write( "x = 3in, the width.  Length is 7in   (3+4)
\n" );
document.write( "CHECKING our Answer
\n" );
document.write( "2*3in + 2*7in = 6in  + 14in = 20in \n" );
document.write( "
