How many rectangles are there in the given figure?

The logic followed here is;

(let's keep in mind the base, means how many rectangles are there in the base)

1+2+3+4= 10  (APCQ) 

1+2+3+4= 10  (PFQF)

And, the other rectangles are;

ALND, LBEN, BMEO, MCFO, ACDF, LCFN, BCEF, ABED, AMOD, LMON

Therefore, the total number of rectangles in the above figure are 10+10+10= 30 rectangles..
