\n" ); document.write( "***
\n" ); document.write( "let x=width of rectangle
\n" ); document.write( "x+8=length of rectangle
\n" ); document.write( "width*length=area
\n" ); document.write( "x(x+8)=105
\n" ); document.write( "x^2+8x=105
\n" ); document.write( "x^2+8x-105=0
\n" ); document.write( "(x+15)(x-7)=0
\n" ); document.write( "x=-15 (reject)
\n" ); document.write( "or
\n" ); document.write( "x=7
\n" ); document.write( "width of rectangle=7 inches \n" ); document.write( "

\n" );
