Length =L
\n" ); document.write( "Width=W=L-3
\n" ); document.write( "Area=A=4ft^2\r
\n" ); document.write( "\n" ); document.write( "Area= Length*Width
\n" ); document.write( "A=L*W
\n" ); document.write( "\"4=%28L%29%28L-3%29\"
\n" ); document.write( "\"4=L%5E2-3L\"
\n" ); document.write( "\"L%5E2-3L-4=0\"
\n" ); document.write( "Solve for L
\n" ); document.write( "\"L%5E2-4L%2BL-4=0\"
\n" ); document.write( "\"L%28L-4%29%2B1%28L-4%29=0\"
\n" ); document.write( "\"%28L-4%29%28L%2B1%29=0\"
\n" ); document.write( "\"L-4=0\" OR \"L%2B1=0\"
\n" ); document.write( "\"L=4\" OR \"L=-1\" (unacceptable) \r
\n" ); document.write( "\n" ); document.write( "so L=4\r
\n" ); document.write( "\n" ); document.write( "Length =L = 4 ft
\n" ); document.write( "Width=W=L-3 = 4-3 = 1ft\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "
