Answer 1

Answer:54.6

Step-by-step explanation:

We have been given that Sunita creates a scale model of an aeroplane. The scale of the model is 5 cm to 13 m. Sunita's model has a wingspan of 21 cm. We are asked to find wingspan of the real aeroplane.

We will use proportion to solve our given problem.

Wingspan of real plane Real length

___________________ = ________

wingspan of model plane scale length

Wingspan of real plane 13

___________________ = ________

21 5

Wingspan of real plane = 13/5×24

Wingspan of real plane = 54.6m
