\n" ); document.write( "The width of a rectangle is 1/4 of the length. The area is twice the perimeter. What are the dimensions of the rectangle?
\n" ); document.write( "


\n" );
document.write( "Let width of rectangle be W
\n" );
document.write( "Then length = 4W
\n" );
document.write( "Area of rectangle: W(4W), or 
\n" );
document.write( "Perimeter of rectangle: 2(W + 4W), or 2(5W), or 10W
\n" );
document.write( "Therefore, we get: 
\n" );
document.write( "
\n" );
document.write( "
\n" );
document.write( "4W(W – 5) = 0
\n" );
document.write( "W – 5 = 0              OR          4W = 0
\n" );
document.write( "W, or width =       OR           W = 0 (ignore)
\n" );
document.write( "Length: 4(5), or  units of length   \n" );
document.write( "

\n" );
