Answer:

The scale factor is k = 1/30

a)

The length of the wing on the model:

  • 9 m * 1/30 = 900 cm * 1/30 = 30 cm

b)

The area of the tail section of the plane:

  • 80 cm² : (1/30)² =
  • 80 cm² * 900 =
  • 72000 cm² =
  • 72000 * (1/100)² m² =
  • 7.2 m²

Answer:

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
