Discussion

Explanation:

Let the length of the sides of the square be 2s.

Consider ∆BQF,

BF = s

In 30° - 60° - 90° triangle,

QF = s3

∴ Area of ∆BQF = 12 × s × s3

Area of ABQCDP = Area of square ABCD – 4 × Area of ∆BQF =4s2-412×s×s3

∴ Required ratio = 4s2-412×s×s3412×s×s3 = 23-1

Hence, option (e).
