\n" );
document.write( "Let width be W
\n" );
document.write( "Then length = W + 4
\n" );
document.write( "Since area = , then we can say that: W(W + 4) = 45
\n" );
document.write( "
\n" );
document.write( "This is the quadratic equation you'd need to solve for W, or the width. You can then determine the length.
\n" );
document.write( "Notice that it can be factored, so it's easy to determine the dimensions of the rectangle. \n" );
