Pls help with part b only thank you​

The scale factor is k = 1/30

a)

The length of the wing on the model:

b)

The area of the tail section of the plane:

The real plane's tail section is 2400 cm^2

Step-by-step explanation:

Well since the model is 1/30 of the real planes size

By multiplying the area of the tail section by 30 we should get the area of the real tail section in the plane

80*30= 2400 cm^2

The real plane's tail section is 2400 cm^2
