width is x
\n" ); document.write( "length is x-13
\n" ); document.write( "area is x^2-13x=90
\n" ); document.write( "so x^2-13x-90=0
\n" ); document.write( "(x-18)(x+5)=0
\n" ); document.write( "x=18 cm only positive root
\n" ); document.write( "x-13=5 cm
\n" ); document.write( "it is 18 cm wide and 5 cm long
\n" ); document.write( "
\n" );
