How many squares are there in the following figure?

66

The number of squares in below diagram are;

ROW = 05, COLUMN = 03

Row is not equal to Column

And, the logic followed here is;

Row's highest number is 05

Column's highest number is 03

So, 05x03= 15                 (multiply until Row or Column becomes zero)

04x02= 08

03x01= 03

02x0= 0

Therefore, 15+08+03= 26 number of squares 

(ii) 

ROW = 03, COLUMN = 06

Row is not equal to Column

The logic followed here is;

Row's highest number is 03

Column's highest number is 06

So, 03x06= 18                     (multiply until Row or Column becomes zero)

02x05= 10

01x04= 04

0x03= 0

Therefore, 18+10+04= 32 number of squares

(iii)

So, 02x02= 04                    

01x01= 01

0x0= 0

Therefore, 04+01+0= 05 number of squares

(iv) Remaining square 01 is;

Therefore, 26+32+05+01+02= 66 square in the figure.
