Of the two square fields, the area of the one is 1 hectare, while anothe one is broader by 1%. There differences in area is:	Select the correct option
A) 201 m ( power ) 2
B) 220 m ( power ) 2
C) 211 m ( power ) 2
D) 219 m ( power ) 2
E) 205 m ( power ) 2

Rationale: area of one square field = 10000 m ( power ) 2 10000 × 1 = 10000 side of this field = √ 10000 m = 100 m side of another square = 101 m difference of areas = [ 101 ( power ) 2 - 100 ( power ) 2 ] m ( power ) 2 [ 101 + 100 ] [ 101 - 100 ] m ( power ) 2 ( 201 ) ( 1 ) m 2 = 201 m ( power ) 2 answer is a .
Answer: A
