The length of a rectangular field is 100 m and its breadth is 40 m. What will be the area of the field?

A) \( \Large (4\times 10^{2}) \)sq m

B) \( \Large (4\times 10) \)sq m

C) \( \Large (4\times 10^{4}) \)sq m

D) \( \Large (4\times 10^{3}) \)sq m

Correct answer:
D) \( \Large (4\times 10^{3}) \)sq m

Description for Correct answer:
Requnred area = \( \Large Length\times Breadth \)

= \( \Large 100\times 40 \)=4000 sq m

= \( \Large (4\times 10^{3}) \) sq m
