Question 50 Similarity Exercise 13.3

A model of a ship is made to a scale of 1 : 200.

If the length of the model is 4 m, find the length of the ship.

Solution:-

The ratio between comparable measurements of an object and a representation of that object is known as a scale factor in mathematics. The copy will be larger if the scaling factor is a whole number. A fractional scaling factor means that the duplicate will be smaller.

From the question it is given that, a model of a ship is made to a scale of 1 : 200

Given, the length of the model is 4 m

Then, length of the ship = (4 × 200)/1

= 800 m
