Answer:
144 yards
Explanation:
A labeled exhibit of the zoo fenced area can be seen in the picture attached below, based on the specification provided within the question. Using these specifications we can calculate the perimeter of the fence by adding all of the sides together, like so
22 yards + 22 yards + 50 yards + 50 yards = 144 yards
Therefore the perimeter of the fence is a total of 144 yards.
