The length of a rectangle is 2 more than twice the width.
\n" ); document.write( "

\r\n" );
document.write( "    L = 2W + 2\r\n" );
document.write( "

\n" ); document.write( "Find the dimensions of the rectangle if the perimeter is 76.
\n" ); document.write( "

\r\n" );
document.write( "    P = 2L + 2W\r\n" );
document.write( "   76 = 2(2W + 2) + 2W \r\n" );
document.write( "   76 = 4W + 4 + 2W\r\n" );
document.write( "   76 = 6W + 4\r\n" );
document.write( "   72 = 6W\r\n" );
document.write( " 72/6 = W\r\n" );
document.write( "   12 = W\r\n" );
document.write( "\r\n" );
document.write( "    L = 2W + 2\r\n" );
document.write( "    L = 2(12) + 2\r\n" );
document.write( "    L = 24 + 2\r\n" );
document.write( "    L = 26\r\n" );

\r\n" );
document.write( "If you're talking about the same rectangle, then the best expression for the\r\n" );
document.write( "perimeter is P = 76. \r\n" );
document.write( "\r\n" );

document.write( "the perimeter by x. P and L will also be different.  You didn't give any facts\r\n" );
