Question

Given the formula for the perimeter of a rectangle where l represents the length and w represents the width.

Answer 1

For this one, I would go with D.

D makes the most sense, giving that there is two sets of each and, that it is just a shorter way to say "add all the sides."  

B and C would only give us half or part of the perimeter and then A does not make much sense.

D would be the answer through process of elimination.

Answer 2

The answer would be b) the 2 represents the two width pairs
