Question

The number of squares in the given figure is: 

• A. 21
• B. 24
• C. 30
• D. 25

Hint:

In grid-based figures, count all sizes of squares from 1×1 to n×n by squaring the possible top-left positions.

Answer 1

The Correct Option is C

Assuming the figure is a 4×4 grid of small squares, count all possible square sizes:

\(1 \times 1\) squares: \(4 \times 4 = 16\)
\(2 \times 2\) squares: \(3 \times 3 = 9\)
\(3 \times 3\) squares: \(2 \times 2 = 4\)
\(4 \times 4\) square: \(1\)

Total number of squares = \(16 + 9 + 4 + 1 = \fbox{30}\)
