Given :  Simon makes a model of a boat,  using a scale of 1 : 30

model has a height of 40 cm

To Find : height of the real boat.

Solution :

Scale 1 : 30

1 cm in Model    = 30 cm in actual

=> 40 cm in Model =  40 x 30  cm  in actual

=> 40 cm in Model = 1200  cm  in actual

100 cm = 1 m

=> 40 cm in Model = 1200/100  m  in actual

=> 40 cm in Model = 12   m  in actual  

model has a height of 40 cm

=> height of the real boat = 12 m
