Q's mother is sister of P &  daughter of M.[sex of P and M are not clear]

S is daughter of P and sister of T.  [sex of P and T is not clear]

M's children : Q's mother and P

P's children  :S[female] and T

M is either Grandmother or Grandfather of T

The Logic followed in the given puzzle is :

L x P = 12 x 16 = 192 (Alphabetical numbers of L & P)

P x T = 16 x 20 = 320 (Alphabetical numbers of P & T)

Similarly, K x () = 132 => () = 132/11 = 12 => L

Hence, the missing letter is L

Let the side of the square plot be 'a' ft.
Given area of the plot (a x a) = 289 => a = 17
Length of the fence = Perimeter of the plot = 4a = 68 ft.
