The perimeter of a rectangle is given by:
\n" ); document.write( "P = 2L + 2W Substitute: P = 30, L = 2W+6, and W = W
\n" ); document.write( "30 = 2(2W+6) + 2W Simplify.
\n" ); document.write( "30 = 4W+12+2W
\n" ); document.write( "30 = 6W+12 Subtract 12 from both sides.
\n" ); document.write( "18 = 6W Divide both sides by 6
\n" ); document.write( "3 = W\r
\n" ); document.write( "\n" ); document.write( "The width of the rectangle is 3 inches.
\n" ); document.write( "
\n" );
