Question

How many squares are there in the given figure?

• A. $16$
• B. $17$
• C. $25$
• D. $30$

Answer 1

Answer: (D)

$30$

When there is a $n\times n$ square, then the total number of squares are $\frac{n(n+1)(2n+1)}{6}$.
Here $n=4$ then
Total number of squares= $\frac{4\times 5\times 9}{6}=30$
Hence, option $D$ is the correct answer.
