Question

In a model of a ship The Mask flagstaff is 6 cm high while The Mask of the actual ship is 9 metre high if the length of the ship is 33 M how long is the model of the ship

Answer 1

Answer:

Consider triangle ABC the model of a ship,

triangle DEF the actual ship.

∆ ABC similar ∆ DEF

.: AB/DE=BC/EF=AC/DF

AB=height of mask flagstuff of model ship=6cm

DE=height of mask flagstuff of actual ship=900cm

BC=length of model ship =xcm

EF=length of actual ship=3300cm

AB/DE=BC/EF

6/900=x/3300

x=6×3300/900

x=22cm

.: Length of model ship is 22cm
