Answer:
Let the length of the model ship be \[x\,\,cm\]. We form a table as shown below:
More the length of the ship, more would be the length of its mast. Hence, this is a case of direct proportion. That is, \[\frac{{{x}_{1}}}{{{y}_{1}}}=\frac{{{x}_{2}}}{{{y}_{2}}}\] \[\Rightarrow \] \[\frac{28}{12}\,=\frac{x}{9}\] \[\Rightarrow \] \[12x=28\times 9\] \[\Rightarrow \] \[x=\frac{28\times 9}{12}\] \[\Rightarrow \] \[x=21\] Hence, the length of the model ship is 21 cm. Actual ship Model Length of the ship 28 m \[x\] Height of the mast 12 m 9 cm
