You can put this solution on YOUR website!
Perimeter = 2(length+breadth)
\n" ); document.write( "=2(3x+x+2)
\n" ); document.write( "=2(4x+2)
\n" ); document.write( "=8x+4
\n" ); document.write( "Since the perimeter is required to be 40yds,
\n" ); document.write( "8x+4=40
\n" ); document.write( "8x=36
\n" ); document.write( "x=4.5\r
\n" ); document.write( "\n" ); document.write( "
\n" ); document.write( "
\n" );
