Of the square fields the area of the one is 1 hectare, while the another one is broader by 1% the difference is area is?

Correct Answer: 201 sq. metres

Explanation:

Area of the square field = 1 hectare
= 10000 m2
Side of the square = √ 10000 m = 100 m
Side of another square field = 100 + 1 = 101 m
∴ Required difference of area
= [(101)2 - (100)2] m2
=[(101 + 100 ) (101 - 100) ] m2
= 201 m2
