width=x
\n" ); document.write( "length=y
\n" ); document.write( "half the perimeter is x+y=20
\n" ); document.write( "but x=(1/4)y
\n" ); document.write( "so y+(1/4)y=20
\n" ); document.write( "(5/4)y=20
\n" ); document.write( "y=20(4/5)=16 cm length
\n" ); document.write( "width is (1/4)16=4 cm width
\n" ); document.write( "Perimeter is 2x+2y=40 cm
\n" ); document.write( "
\n" ); document.write( "
\n" );
