area of a square is 1 / 2 hectare . the diagonal of the square is ?
area = 1 / 2 hectare = 10000 / 2 m 2 = 5000 m 2 again area = 1 / 2 x ( diagonal ) 2 so 1 / 2 x ( diagonal ) 2 = 5000 m 2 diagonal 2 = 10000 diagonal = 100 answer : b
sqrt(multiply(const_2, multiply(divide(1, 2), multiply(const_100, const_100))))
