In ship of length 28m, height of its mast is 12m. If the height of the mast in its model is 9cm what is the length(in cm) of the model ship?
height of its mast is 12m=12×100 cm=1200 cm
height of the mast in its model is 9cm
So, ratio=height of the mast in its modelheight of original mast=91200
So, height in model decreases by this ratio.
This same ratio will be there for length of ship and its length in model
length of original ship =28 m=28×100=2800 cm
So, length of ship in the model = ratio x length of original ship
=91200×2800=93×7=21 cm
