When plotting spalls as polygons, which step comes immediately before the final step of adding the estimated number?

Explanation:
When you’re plotting spalls as polygons, you first need a closed boundary so you have a well-defined area to work with. The step that comes right before adding the estimated number is connecting the end points to complete the polygon. Closing the shape makes sure the boundary is continuous and that the area is accurately represented, which is essential before you can estimate how many spalls fit inside. Plotting the ending width perpendicular to the first line is a construction detail for shaping the figure but doesn’t finalize the boundary. Connecting the beginning and ending centerpoints would create an internal line rather than closing the outer boundary. Marking the estimated number is the final action, after the polygon is closed and the area is established.
