Polygons in 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 perimeter of the shape?

• 20 units

• 12 units squared

• 22 units

• 32 units squared

What is the area of the shape?

• 35 units squared

• 24 units squared

• not enough information

• 22 units squared
