A rectangular hall 108 meters long is paved with 7128 tiles each measuring 5 \( \Large dm^{2} \), then Width of the plot is

A) 3.3 m
B) 330 m
C) 33 m
D) 0.33 m

Correct Answer:

A) 3.3 m

Description for Correct answer:
\( \Large 108 \times b = 7128 \times 5 \times \left(\frac{1}{10}m\right)^{2} \)

\( \Large \left(\because\ 1 m^{2} = 100\ dm^{2}\right) \)

Therefore, Width of plot, b = 3.3 m
