A model aircraft is made to a scale of 1:48. The area of the wing of the real aircraft is 52 m². What is the area of the wing of the model?

0.0226 m²

0.226 m²

2.496 m²

2496 m²

The scale factor is 48. Then, Area scale factor is 48² = 2304. The area of the wing on the model is = 52/2304 ≈ 0.0226 m²
