Answer 1

Correct answer is (a) It is the ratio of square of wing span to wing area

Best explanation: Aspect ratio is the ratio of the square of wing span to wing area. It is given by the formula, AS=\(\frac{b^2}{S}\) where AS is aspect ratio, b is wing span and S is wing area.  In general the aspect ratio is maintained high in the aircraft for structural rigidity and reducing drag.
