Method 1

1,66*6 = 9,96 metre
We took a picture of the tree  where a person  was standing next to it and sent it to the computer, then we found out how many times the person could be put on top of himself to reach the top of the tree. We used paint to draw the lines.

Method 2

9,30 metre
We found a stick that was the length of the persons arm. Then we held the stick in stretched arm. We walked backwards until the tree is covered by the stick in the height. The distance from the tree and where the person was standing is the same height as the tree.

Method 3

We can’t make method 3 right now because the sun doesn’t shine.

Which problems is there whit the methods?

The advantages whit the methods are that, it’s easy and quick to find the result, but the drawback whit the methods is that they don’t give the exact result.

Which method is the right?

We think that it is method 3 there is the right, but we don’t, now because we didn’t make it. Between method 1 and 2, we think that method 2 gives the most correct answer, if we do it exact. But it is difficult to do it precise. So it is easy to make method 1 by rule of thumb.
