Count the number of squares in the given figure.
Simplest squares are EFRQ, MQYX, QRZY, RNSZ, LXWK, XYA1W, YZB1A1, ZSTB1, SGHT, WA1VP, A1B1UV, B1TOU and VUIJ i.e. 13 in number.
The squares having two components each are AEYL, FBGZ, KA1JD, B1HCI i.e. 4 in number.
The squares having four components each are MRB1W, QNTA, XZUP and YSOV i.e. 4 in number.
The squares having seven components each are AFB1K, EBHA, LZID, and YGCJ i.e. 4 in number.
There is only one square having nine components i.e. MNOP.
There is only one square i.e. ABCD composed of seventeen components.
So, total = 13 + 4 + 4 + 4 + 1 + 1 = 27
