please tell the answer of this question with solution.​

Answer 1

Answer:

21 cm

Step-by-step explanation:

For a 12 m high mast, the height of mast of model ship =9 cm=0.09m

For a 1 m high mast, the height of mast of model ship =

12

0.09 m

Therefore, the ratio of dimensions of model ship and actual ship =

12

0.09 m

For a 1 m long ship, length of model ship =

12

0.09 m

For a 28 m long ship, length of model ship =

12

0.09 m

∗28=0.21m=21 cm

Answer 2

Answer:

The mast of the actual ship is m high =12

The lengthy of the ship is m =28

12×2=24+4=28

The mast is 9 cm high

The modle ship is =22.

9×2=18+4=22.

So your answer is 22.
