How many squares are there in the given figure?
Let's calculate the total number of squares present in the given figure step-by-step.
To systematically count the number of squares, we consider squares of different sizes.
- Count the smallest squares (1x1):
- There are 4 smallest squares within the top-left block.
- Another 4 smallest squares within the middle block.
- There are 6 separate small squares around the structure.
- Total = 4 + 4 + 6 = 14 squares of size 1x1.
- Count the medium squares (2x2):
- There is 1 medium square inside each 4x4 structure (top-left and center), contributing 2 squares.
- Additionally, other 2x2 squares can form using combinations of the 1x1 squares surrounding these blocks.
- Total = 2 (inside the 4x4 blocks) + 3 (from surrounding combinations) = 5 squares of size 2x2.
- Count the large squares (3x3 and 4x4):
- There are no 3x3 squares because such combinations cannot form given the structure.
- There are 2 squares of 4x4 size (considering combinations of 4 2x2 squares).
- Total = 2 squares of size 4x4.
So, adding up all the different squares we have:
- Total = 14 (1x1) + 5 (2x2) + 2 (4x4) = 21 squares.
Thus, the total number of squares in the given figure is 21. The correct answer is 21.
