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?

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
