In a model of factory, the chimney is 9 cm high while the chimney of the actual factory is 12 m high. If height of the actual factory is 28 m, find the height of the model of factory.​

Answer 1

Answer:

hello bro

Step-by-step explanation:

Given that the mast of the model ship is 9 m high, while the mast of the actual ship is 12 m.

If the length of the ship given is 28m then,

Length of the model ship can be obtained from the direct proportion relation of mast height and length of ship.

We obtained the relation:

So, by the relation we have;

Let us assume that the length of model ship is 'x'

after solving this relation we get,

,

Length of the model ship is 21cm.

Answer 2

Answer:

Found the answer through ratio and proportion.

U can use algebraic expressions too.

Step-by-step explanation:

let the height of the model factory be = x

therefore :-

9:x::1200:2800

=> 9/x = 1200/2800

=>1200x = 9 × 2800

=> x = 9×2800/1200

=> x = 21cm

hope it helped :)
