Let x=length
\n" ); document.write( "y=width\r
\n" ); document.write( "\n" ); document.write( "Area is 108 cm2
\n" ); document.write( "
xy=108
\r
\n" ); document.write( "\n" ); document.write( "Since the ratio of width to length is 2:5,
\n" ); document.write( "Let x=5a
\n" ); document.write( "y=2a\r
\n" ); document.write( "\n" ); document.write( "Then
\n" ); document.write( "
xy=(2a)(5a)=10a2=108
\n" ); document.write( "a2=10.8
\n" ); document.write( "a=3.286 approx.\r
\n" ); document.write( "\n" ); document.write( "So,\r
\n" ); document.write( "\n" ); document.write( "x=5a=16.43 cm
\n" ); document.write( "y=2a=6.572 cm\r
