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: Choose the correct choice from the following answers
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
201 m(power)2rea 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) m2 = 201 m(power)2   201 m(power)2nswer is 201 m(power)2.
