Graphing polygons in the coordinate plane

You design a tree house using a coordinate plane. You plot the vertices of the floor at J (2, 1), K (2, 8), L(9, 8), and M (9, 1). The coordinates are measured in feet. What is the area of the tree house?

Prior to going, Ryan read that the lobster population in the area labeled 𝑊𝐺𝐻𝑅 is estimated to be 2500 lobsters.

Determine the density of the lobster population in the area labeled WHGR.

A map of a zoo shows the animal exhibits on a coordinate grid with each square on the grid representing 100 feet by 100 feet. The exhibit for the elephants, rhinoceroses, and hippopotamuses is shown as a polygon-shaped area with the vertices listed below.

Southwest corner (1,6), Northwest corner (3,9),(Northeast corner)(7,9), Southeast corner (5,6)

What is the distance between the northwest and northeast corners of the area?
