This is simular to the one I answered earlier...\r
\n" ); document.write( "\n" ); document.write( "There are 3 feet in a yard. \r
\n" ); document.write( "\n" ); document.write( "The width of the room in feet is: 3*W
\n" ); document.write( "The length of the room in feet is: 3*L
\n" ); document.write( "The area of the room in square feet is: (3*W)(3*L)=9WL
\n" ); document.write( "The cost is $.10 * 9WL = $.90WL
\n" ); document.write( "This makes sense because it equates to 90 cents a square yard and there are 9 square feet in a square yard.
\n" ); document.write( "
\n" );
