Answer:

36 m.

Step-by-step explanation:

We are asked to find the final elevation of a bird that stats at 20 m and changes 16 m.  

[tex]\text{Bird's final elevation}=\text{Bird's initial level}+\text{Change in bird's elevation}[/tex]

Since the bird's initial elevation is 20 m and it changed 16 m in positive direction, so bird's final elevation will be:  

[tex]\text{Bird's final elevation}=\text{20 m}+\text{16 m}[/tex]

[tex]\text{Bird's final elevation}=\text{36 m}[/tex]

Therefore, bird's final elevation will be 36 m.
