Question

The scale factor of a model plane to the actual plane is 1 to 25.

Find the wing area of the model if the wing area of the actual plane is 300 ft2
.

Answer 1

Explanation:

Length on model : Length on actual = 1 : 25

=> Area on model : Area on actual

= 1² : 25² = 1 : 625.

Therefore area on model = 300ft² * (1/625) = 0.48ft².
