Let l be the length of rectangular frame
\n" ); document.write( "let b be the breadth of rectangular frame.
\n" ); document.write( "= l:b=4:3
\n" ); document.write( "= l=4/3b
\n" ); document.write( "As b=42cm
\n" ); document.write( "so, l=4/3*42
\n" ); document.write( " l=56cm
\n" ); document.write( "Total frame required will be
\n" ); document.write( " =2(l+b)
\n" ); document.write( " =2(56+42)
\n" ); document.write( " =2(98)
\n" ); document.write( " =196cm
\n" ); document.write( "
\n" );
