Because the scale is 200 meters long per unit line segment, the supermarket measured in the municipal government is 4 unit line segments long.
Therefore, the distance is 200×4=800 meters;
According to legend, the library is located 30 degrees northeast of the municipal government;
The measurement length of the library in the municipal government is 3 units, so the distance is 200×3=600 (meters);
(3) Xinhua Bookstore is located 30,300 meters southwest of the municipal government.
Because the scale is 200 meters per unit line segment,
300÷200= 1.5 (pieces),
According to the above analysis, draw the following figure:
So the answer is: East, 800, North, East, 30,600;
