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
