Length = 2x-3
\n" ); document.write( "Width = x
\n" ); document.write( "Perimenter = 42
\n" ); document.write( "Formula = 2(L+W)=P
\n" ); document.write( "2(2x-3+x)=42
\n" ); document.write( "2(3x-3)=42
\n" ); document.write( "6x-6=42
\n" ); document.write( "6x=48
\n" ); document.write( "x=8
\n" ); document.write( "2(8)-3=13\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Hence the width is 6m and the length is 9m.
