Find the number of squares.

The correct answer is Option (3) → 14

The figure is a 3 × 3 grid. Squares are counted size by size: a square of side \(k\) small squares can be placed in \((4-k)^2\) positions.

• 1 × 1 squares: \(3\times3=9\)

• 2 × 2 squares: \(2\times2=4\)

• 3 × 3 square (the whole figure): 1

• Total \(=9+4+1=14\)

Tip: For an \(n\times n\) grid the number of squares is \(1^2+2^2+\dots+n^2\); for \(n=3\) it is \(1+4+9=14\).
