  2. 34 trees

    he will make 17 rows of two trees each = 17 rows (34 tress)

    now if we conside the first trees in each it can be considered as 1 row
    |||ly for the second tree = 2 rows (0 tree req.)


    therefore the answer

    1. How? I get only 17 rows like this.

      Each square gives you 7 rows (3 vertical, 3 horizontal, 1 diagonal). That is 14 rows. Plus you get 1 long diagonal, which now makes total of 15 rows.
      Now we need 4 more rows, but there can be found only 2 more - 2 rows with 4 trees on each, making the total of 17 rows. Still missing 2 rows?

    1. Explain please.
      Only 14 rows you have there. Where do you take the needed 5 more?

  8. The answer is 2, the question was "what is the MINIMUM number of trees required by the gardener to have 19 rows of trees" The statement before the question gave away the answer suggesting that there should be more that 2 trees to make a row.

    1. 2 (minimum) * 19 = 38
      38 is the minimum number of trees to make 19 rows

    2+3+4+5+...+19+19 = 208

  11. Just need 5 trees in one main row, since there are 25 rows within it

    1 row of 5
    5 rows of 4
