Count the number of squares in the given figure.

32
30
29
28
Answer: Option
Explanation:

The figure may be labelled as shown.

The simplest squares are ABGF, BCHG, CDIH, DEJI, FGLK, GHML, HINM, IJON, KLQP, LMRQ, MNSR, NOTS, PQVU, QRWV, RSXW and STYX i.e. 16 in number.

The squares composed of four components each are ACMK, BDNL, CEOM, FHRP, GISQ, HJTR, KMWU, LNXV and MOYW i.e. 9 in number.

The squares composed of nine components each are ADSP, BETQ, FIXU and GJYV i.e. 4 in number.

There is one square AEYU composed of sixteen components.

There are 16 + 9 + 4 + 1 = 30 squares in the given figure.

Give the number to rows and columns. As 1234 are rows and 1234 are columns. Then,

4x4 = 16.
3x3 = 9.
2x2 = 4.
1x1 = 1.

Add 16 + 9 + 4 + 1 = 30.
So, the Answer is 30.

In this problem base (n) = 4.
Hence,
1^2+2^2+3^2+4^2 = 30.

FOUR COLUMNS 4^2 + 3^2 + 2^2 + 1^2 = 16+9+4+1 = 30.

n(n+1)(2n+1)/6 is not the correct formula for finding squares.
