Guidelines to solve Exercise 2 on Page 100 of Math 4 Textbook

Solution Method:
According to the area measurement table:
- Order of measurement units: 
+ Greater than square meters: Km² (square kilometers); hm² (hectare); dam² (decameter square); m² (square meters)
+ Intermediate measurement unit: Square meters
+ Smaller than square meters: Dm² (square decimeters); cm² (square centimeters); mm² (square millimeters)
- Each area measurement unit is 100 times the next smaller unit
- Each area measurement unit is 1/100 of the next larger unit.
