Answer:
410 people
Explanation:
The total number of people in the park is the sum of the number of boys and the number of girls. Then, the total number is:
210 + 197 = 407 people
Now, to round to the nearest 10, we need to know that 407 is a number between 400 and 410. Then, 407 is more close to 410, so 407 rounded to the nearest 10 is 410.
