2L + 2W = Perimeter
\n" ); document.write( "2L + 2W = 84
\n" ); document.write( "and we have that:
\n" ); document.write( "L = 2W + 6
\n" ); document.write( "Rewrite substituting for L:
\n" ); document.write( "2(2W + 6) + 2W = 84
\n" ); document.write( "4W + 12 + 2W = 84
\n" ); document.write( "6W = 72
\n" ); document.write( "W = 12
\n" ); document.write( "So now we know that the width is 12. Let's find the length:
\n" ); document.write( "L = 2W + 6
\n" ); document.write( "L = 2(12) + 6
\n" ); document.write( "L = 24 +6 = 30
\n" ); document.write( "The length is 30
\n" ); document.write( "~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
\n" ); document.write( "Check:
\n" ); document.write( "2L + 2W = 84
\n" ); document.write( "2(30) + 2(12) = 84
\n" ); document.write( "60 + 24 = 84 Correct
\n" ); document.write( "
\n" );
