The perimeter of a rectangle is found by using the formula: 2L + 2W.
\n" ); document.write( "if the perimeter of a rectangle is 66 cm, and the length is twice the width
\n" ); document.write( "what is the length?\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "2L + 2W = 66:
\n" ); document.write( "\"the length is twice the width\"; therefore
\n" ); document.write( "L = 2W
\n" ); document.write( "replace L with 2W
\n" ); document.write( "2(2W) + 2W = 66
\n" ); document.write( "4W + 2W = 66
\n" ); document.write( "6W = 66
\n" ); document.write( "W = 66/6
\n" ); document.write( "W = 11 cm
\n" ); document.write( "therefore
\n" ); document.write( "2(11) = 22 cm is the length
\n" ); document.write( "
\n" );
