Area of a Quadrilateral

Jack has decided to open a zoo with only the most interesting animals he can think of. He has chosen to include seven rare animals in this zoo and must build enclosures that allow each animal to feel at home.

After much deliberation Jack has decided to include a pangolin, a narwhal, an okapi, an aye aye, a naked mole rat, a pink fairy armadillo, and a sunda colugo.

Thus far Jack has built three enclosures for these animals:

• The narwhal's enclosure is a square and has a perimeter of $200$ meters.
• The pangolin has a rectangular enclosure that is $10$ meters wide and $12$ meters long.
• The pink fairy armadillo is also in a square enclosure that has a perimeter of $64$ meters.
