Rectangle	Length (units)	Width (units)	Area (square units)
A	$x + 3$	$x - 4$
B		$3 x - 5$	$9 x^{2} - 25$
C			$x^{2} + 8 x + 16$
D	$x - 2$		$2 x^{2} - 3 x - 2$
E		$x + 6$	$x^{2} + 4 x - 12$
F			$x^{2} - 16$
G	$3 x - 5$	$3 x - 5$
H	$3 x - 1$	$x + 2$
I	$2 x - 3$		$4 x^{2} - 12 x + 9$
J			$x^{2} + 6 x - 16$
K	$2 x + 3$	$2 x - 3$
L			$4 x^{2} - 12 x y + 9 y^{2} - 25$
