To find the wingspan of the real aeroplane, you can use the scale ratio. Since the model is at a scale of
, you simply multiply the model’s wingspan by 40. So,
or
. Thus, the wingspan of the real aeroplane is 10 metres.
For the model aeroplane’s length based on the real aeroplane’s length of 8 metres, convert the length to centimetres first:
. Then, divide by the scale factor (40):
. Therefore, the length of the model aeroplane is 20 centimetres.
