Aspect ratio is given by the formula:
- Mean Chord / Span.
- Span^2 / Area.
- Span^2 / Mean Chord.
Explanation
Aspect ratio equals span divided by mean chord, and since area equals span times mean chord, this is equivalent to span squared divided by area. Both forms give the same value; mean chord divided by span is the inverse, so that option is incorrect.

How come?

For most of the wings the length of the chord isn't constant but varies along the wing (ie. High aspect & Low aspect Ratio wing).
SO, ----Aspect ratio is defined as the square of wingspan divided by the area of the wing ie AR= (WING-SPAN)^2/ WING AREA.
Simply,
(i think u have understood AR in this sense)
Aspect Ratio = Span/mean chord. (wing)
multiply top and bottom by "SPAN"
then u'll obtain
AR= (WING-SPAN)^2/ WING AREA.
cheers :)
