I'm terrible at math any here is appreciated.

  d.  12 units, 14 units, 10 units

Step-by-step explanation:

The side lengths differ by 2 units from one to the next larger one:

  (2t+2) - (2t) = 2

  (2t+4) - (2t+2) = 2

So, you're looking for answer numbers that can make a sequence with differences of 2, and that add to 36. Only the last choice matches that description.

You can solve this "directly" by adding up the side lengths and setting that result to the perimeter length.

  (2t+2) + (2t+4) + (2t) = 36

  6t +6 = 36 . . . . . collect terms

  6t = 30 . . . . . . . . subtract 6

   t = 30/6 = 5 . . . . divide by 6

The shortest side is 2t, so is 2·5 = 10 units. Only the last answer choice matches this.

  Side lengths are 12 units, 14 units, 10 units.
