A) \[38\text{ }c{{m}^{2}}\]
B) \[243\text{ }c{{m}^{2}}\]
C) \[171\text{ }c{{m}^{2}}\]
D) \[196\text{ }c{{m}^{2}}\]
Correct Answer: C
Solution :
: Area of 1 small square \[=(3\times 3)c{{m}^{2}}\] \[=9c{{m}^{2}}\] Number of shaded squares =19 \[\therefore \] Shaded area \[=19\times 9=171c{{m}^{2}}\]
