let the width be x inches\r
\n" ); document.write( "\n" ); document.write( "the length is x+8\r
\n" ); document.write( "\n" ); document.write( "Area of rectangle = L * W\r
\n" ); document.write( "\n" ); document.write( "x(x+8)=48\r
\n" ); document.write( "\n" ); document.write( "x^2+8x=48
\n" ); document.write( "x^2+8x-48=0\r
\n" ); document.write( "\n" ); document.write( "x^2+12x-4x-48=0\r
\n" ); document.write( "\n" ); document.write( "x(x+12)-4(x+12)=0\r
\n" ); document.write( "\n" ); document.write( "(x+12)(x-4 ) = 0\r
\n" ); document.write( "\n" ); document.write( "x= -12 Or 4\r
\n" ); document.write( "\n" ); document.write( "So width = 4 inches\r
\n" ); document.write( "\n" ); document.write( "Length =12 inches\r
