# A rectangular garden plot has sides of the length shown. Yolanda says that the perimeter of the plot is 2p+2q. Nico says that the perimeter is 2(p+ q). What property of numbers tells you that they are both correct?

The distribution property tells you they are both correct. Because, using the distribution property on $2 \left(p + q\right)$ gives:
$2 \left(p + q\right) \to 2 p + 2 q$
