# 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

 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
