Please help me with this problem. I don’t understand it.

34

Explanation:

mid point of 0 and 3 is 1.5, -1 to 0 is 1, so the average value over that is 1.5

then 3 to 1, mid point is 2, with a lenght of 1, so 1.

midpotni of 1 and 5 is 3, over a length of 2, so 6

5 and 8 -> 6.5, length of 2 -> 13

8 and 4 -> 6, length of 1 -> 6

4 and 9 -> 6.5, length of 1 -> 6.5

add em up

1.5+1+6+13+6+6.5 = 34
