Answer:
36 meters
Step-by-step explanation:
The bird starts at 20 and (assuming it goes up) increases by 16 meters. You have to add to get 36. However, if the bird flies 16 meters down, the answer would be four meters. The answer 36 is assuming the bird flies upward.
4 x 4 = 16
5 x 5 = 25
6 x 6 = 36
