Answer 2

Given: a model of a aeroplane is somewhat Triangle in shape is made on the scale of 1 to 100 the model is 150 cm long.

To find: The length of the actual aeroplane​.

Solution:

According to the question, the ratio of the model to the real aeroplane is given as 1:100. This means that one centimetre of the model would be equal to 150 cm of the real aeroplane.

Now, in order to find the length of the actual aeroplane, the following calculations must be made.

$Length = \frac{100 * 150}{1}$

            $= 15000 cm$

So, 150 cm of the model would be equal to 15000 cm in the reality.

Therefore, the length of the actual aeroplane​ is 15000 cm.
