\n" ); document.write( "Convert the given information into like units:

\n" ); document.write( "16 inches is 16/12 = 4/3 feet.

\n" ); document.write( "Area = length * width:

\n" ); document.write( "21 = x(4/3)
\n" ); document.write( "x = (3/4)*21 = 63/4 = 15 3/4

\n" ); document.write( "The required length is 15 3/4 feet, or 15 feet 9 inches.
