Question

in a model of a ship the mast is 9cm 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


​

Answer 1

Answer:

Given that in a model of a ship, the mast is 9 cm high, while the mast of the actual ship is 12 m, i.e., 1200 cm high.

Now, (length of the mast of the model ship) : (length of the mast of the ship) = (length of the model ship) : (length of the ship)

i.e., length of the model ship = 9*2800/1200 cm

i.e., length of the model ship = 21 cm

Hence, if the length of the ship is 28 m, then the length of the model ship is 21 cm.

2.Let x be the length of model Then, 9/x=12/28 9×28/12= x x=21 centimetre.

3.Scale : 9cm :12m

Therefore 1m = 9/12 cm

For 28m -> 9/12 *28 = 21 cm (ans)

4.Through the concept of ratios

9 : 12 = x : 28

Thus x = 21cm

5.In a model, 12m=9cm 1m=9/12cm 28m=9/12*28=21cm

6.Let x be the length of model Then, 9/x=12/28 9×28/12= x x=21 centimetre

7.Let x be the length of model Then, 9/x=12/28 9×28/12= x x=21 cm

8.model ship actual ship

mast = 9cm 12m

length= ?? 28m

since 1m = 100cm

so 12m =1200cm

28m= 2800cm

=> (2800*9)/1200

=> 21cm
