Polygons in a 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?

• 28 feet²

• 49 feet²

• 56 feet²

• 64 feet²

What is the area of the shape?

• 35 units squared

• 24 units squared

• not enough information

• 22 units squared

The vertices of the giraffe exhibit at a Zoo are E(0,90), F(60, 90), G (100,30), and H (0,20). The coordinates are measured in feet. What is the area of the exhibit?

• 72 feet²

• 48 feet²

• 4800 feet²

• 7200 feet²

• 9600 feet²

The drawing shows points  ^A,B, and ^C. At what location would you add point ^{D to create a square ?}

• ( 2,1 )

• (4,5)

• ( 5, 4 )

• ( 5, 10 )

Graph a polygon with vertices located at (0, 2), (5, −3), (−2, −4), and (−4, 0).

A polygon has vertices ​(−​4,8), ​(4,8), (4,1),​ (9,1), ​(12,−​7), and ​(−​4,−​7). Graph the polygon on the coordinate plane.
