To convert from square centimeters to square inches, we need to divide by the conversion factor $(2.5 	ext{ cm/in})^2 = 6.25 	ext{ cm}^2/	ext{in}^2$. So, $29 	ext{ cm}^2 \div 6.25 	ext{ cm}^2/	ext{in}^2 \approx 4.64 	ext{ in}^2$, rounded to 2 decimal places. Therefore, the correct answer is $\boxed{	extbf{(B)}}$.
