\n" ); document.write( "One way...
\n" ); document.write( "Compute area in square feet:
\n" ); document.write( "\"+9ft+x+21ft+=+189ft%5E2+\"
\n" ); document.write( "Convert square feet to square yards:
\n" ); document.write( "\"189ft%5E2+%2A+%281yd%5E2%2F9ft%5E2%29+=+21yd%5E2\"
\n" ); document.write( "Multiply square yards by price per square yard
\n" ); document.write( "\r
\n" ); document.write( "\n" ); document.write( "------
\n" ); document.write( "I carried along the units to illustrate how they can help keep things straight. For example, in the conversion to square yards, notice how \"ft%5E2\" will cancel, leaving \"+yd%5E2\" \n" ); document.write( "
