Let the width be x.
\n" ); document.write( "Then the length is 3x.
\n" ); document.write( "Perimeter of the rectangle=2(l+b)=2(x+3x)=8x
\n" ); document.write( "8x=200cm
\n" ); document.write( "x=25 cm
\n" ); document.write( "The length of the rectangle is 75 cm.
\n" ); document.write( "The width of the rectangle is 25 cm.
\n" ); document.write( "
\n" ); document.write( "
