Consider L as its length, and W as its width.\r
\n" ); document.write( "\n" ); document.write( "L is 2 inches less than 3 times W. This means that 3W subtracted by 2 would yield L:
\n" ); document.write( "L = 3W - 2
\n" ); document.write( "3W - L = 2 ... (1)\r
\n" ); document.write( "\n" ); document.write( "The perimeter of a rectangle is twice its width summed with twice its length:
\n" ); document.write( "2w + 2L = 28
\n" ); document.write( "simplified, by dividing with 2:
\n" ); document.write( "W + L = 14 ... (2)\r
\n" ); document.write( "\n" ); document.write( "Add up Equations (1) and (2) (in which L will be eliminated, as -L + L = 0):
\n" ); document.write( ".
\n" ); document.write( "3W - L = 2
\n" ); document.write( "1W + L = 14
\n" ); document.write( "-------------- +
\n" ); document.write( "4W = 16
\n" ); document.write( "W = 4
\n" ); document.write( ".
\n" ); document.write( "Because W + L = 14, L = 14 - w = 14 - 4 -> L = 10
\n" ); document.write( "
\n" );
