Write two equivalent expressions to represent the area of the rectangle

The first expression you could set up is just the standard length * width formula, but with the two values substituted for (n - 3) and 2, giving you  . for the second expression, simply distribute the 2 to the n and the 3 to obtain the second expression  .(note that, in both cases, you could use the commutative properties of addition and multiplication to get the expressions  and  )
