correct Question :-

In a model ship, the Mast is 9 cm high, while the Mast of the actual ship is 12 m high. if the Length of the ship is 28 m, how long is the model Ship?

to find :-

how m how long is the model ship ?

solution:-

Let the length of model ship = x

we have table for this

\begin{tabular}{I clc I cl clclcl}</p><p>\cline{1-3} length of actual ship (in m) &amp; 12&amp; 28\\</p><p>\cline{1-3} length of model ship (in cm)&amp; 9&amp;x \\</p><p>\cline{1-3} </p><p>\end{tabular}

\small\underline\textsf{\huge{[}\small{Note:- this is an direct proportion\huge{ ]}}}

\large\implies\tt \frac{12}{9}  =  \frac{28}{x}  \\

\large\implies\tt x + 12

\large\implies\tt28 \times 9

\large\implies\tt x =  \dfrac{\cancel{28 \times 9}}{\cancel{12}}  \\

\large\implies\boxed{\tt 21 cm}

the model ship is 21 cm long.

★ In a model of a ship the mast is 9 cm high ,while the mast of the actual ship is 12m high . If the length of the ship is 28m.How long is the model ship?

Given:

  • Mast of model ship is 9 cm high if the mast of actual ship is 12 m high
  • Length of ship is 28m long

To Find:

  • Length of model ship

Solution: Let length of model ship be x cm if the length of actual ship is 28 cm

Table will be

Length of model ship (in cm) = 9 ⠀⠀ x

Length of actual ship (in m) = 12 28

Now , as length of actual ship increases. Length of actual ship also increases

These are in direct Proportion

\small\implies{\sf } 9/12 = x/28

\small\implies{\sf } (9/12)28 = x

\small\implies{\sf } 252/12 = x

\small\implies{\sf } 21 = x

Hence, Length of Model Ship is 21 m
