In the following figure, find the total number of squares.
Step-by-step Solution:
To find the total number of squares, we need to systematically count all squares of different sizes and orientations.
These are the most obvious squares that make up the main grid. There are 4 columns and 2 rows.
4 * 2 = 8 squares
These are larger squares formed by combining four 1x1 squares. We can find 3 of them by shifting a 2x2 window across the grid.
3 squares
Inside each of the 8 small 1x1 squares, the diagonals form a smaller, tilted square.
8 squares
These are squares of size 1x1, tilted at 45 degrees. They are formed by connecting two adjacent grid points (like B and I) and the centers of the two squares next to that line.
3 + 2 = 5 squares
Finally, we add up the counts from all categories:
8 (1x1) + 3 (2x2) + 8 (small tilted) + 5 (medium tilted) = 24
Final Answer: The total number of squares is 24.
