Demolition mathematics
Solution: (1) According to the functional diagram, the green area at the end of 2003 was 60 hectares, 4 hectares more than that at the end of 2002; In 200 1, 2002 and 2003, the green area increased the most in 2002;

(2) If the growth rate of green area from the end of 2003 to the end of 2004 is X, then there is 60( 1+x)=66. If we solve this equation, it is x= 10%. A: From the end of 2003 to the end of 2004, the growth rate of green area was 10%.
