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 :
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 .
subtract(square_area(add(1, sqrt(multiply(const_10, const_1000)))), multiply(const_10, const_1000))
