First I made equations for the perimeter (p) in terms of the width (w) and same for the length (l).
Then, since all the sides added together equaled the perimeter, I made the perimeter equation equal to all the sides added together, all in terms of width (no other variables than w).
Solving that algebraically, you can find w. And then plug that back into the equation for length to find length.
w=8, l=11

Step-by-step explanation:
Perhaps the easiest way to do this is to draw the needed shape in the box, then locate it among the answer choices. Use the identifying features such as dot location and direction of arrow (or tail).
__
Left-to-right, this is what you're trying to match:
- tail on the right, dot in the tail
- tail on the left, dot in the fin
- tail on the right, dot in the nose
- tail on the left, dot in the center
