Perimeter is the sum of the length of all sides of the rectangle.
\n" ); document.write( "A rectangle has 4 sides (2 lengths and 2 widths).
\n" ); document.write( "Given: length = 2x+4 and width = x
\n" ); document.write( "Perimeter = 2 lengths + 2 widths
\n" ); document.write( "Therefore Perimeter = 2(2x+4) + 2(x)
\n" ); document.write( "Perimeter = 4x+8 + 2x = 6x+8
\n" ); document.write( "
\n" );
