Unit 3 Lessons 12-13: Polygons and the Coordinate
Plane
Model
Structured Guided Practice
Directions: Plot the points. Find the area and the perimeter of the polygon.
Plot the points on the graph. Find the area and the perimeter of the polygon:
(-3, -1) (-3, 3) (3, 3) (3, -1)
 Plot the points, and connect the line segments.
 Find the length of each line segment.
 Multiply the
length
×
width
to find the area.
 Add all of the line segment lengths together
to find the perimeter.
