Solution
We can see that it will be very difficult to count each square individually.
So, we can count the number of squares (along the length) in a row, and multiply it with the total number of rows (squares along the breadth).
Number of rows in the figure = 10
Number of squares in a row = 12
Total number of squares in the figure = 12 x 10 = 120.
