A) \[34\,\,{{m}^{2}}\]
B) \[32\,\,{{m}^{2}}\]
C) \[46\,\,{{m}^{2}}\]
D) \[44\,\,{{m}^{2}}\]
Correct Answer: A
Solution :
[a] Volume of air in room =\[204\,\,{{m}^{3}}\] Area of floor\[\times \]height of room =\[204\,\,{{m}^{3}}\] Area of floor\[\times 6=204\,\,{{m}^{3}}\] .\[\therefore \]Area of floor \[=\frac{204}{6}=34{{m}^{2}}\]
