Perimeter of a rectangle = 2 width + 2 length\r
\n" ); document.write( "\n" ); document.write( "let x be the width
\n" ); document.write( "length = 5x+6\r
\n" ); document.write( "\n" ); document.write( "2x+(5x+6)2 = 312
\n" ); document.write( "2x+10x+12=312
\n" ); document.write( "12x=300
\n" ); document.write( "x=25\r
\n" ); document.write( "\n" ); document.write( "length = 5(25)+6 = 131
\n" ); document.write( "Therefore the width is 25km, the length is 131 km
\n" ); document.write( "
\n" );
