The area of the deck ship is 180,000 m2m^2 . Calculate the area of the deck of the model.
Solution:  
    ∴\;\; \therefore (Scale factor )2=   area of the model      area of the ship   )^2=\frac{\; \text{ area of the model }\;}{\; \text{ area of the ship }\;}
  190,000=   area of the model   1,80,000\; \frac{1}{90,000} = \frac{\; \text{ area of the model }\;}{1,80,000}
area of the model =2m2    =2 m^2 \;\;
