First assignment - Evelina and Linas

Method 1
 

First we measured Linas’s height. It was 1.81 m. Then we measured how many times can Linas be put on top of himself to reach the top of the tree. He can be put on top of himself 4 times.

1.81 x 4 = 7.24 m.

It was easy so we haven’t got any problems.

Method 2
 

First we found a stick that was at least the length as our arms. It was 60 cm long. We hold the stick vertically. Then Linas stood next to the tree and started walking backwards until the stick was as big as the tree. The distance was 9.4 m. In the end we used the similar triangles' properties to calculate the tree's height. The answer was 9.4 m.

 

 
 
 
 
 
 












Method 3

We couldn’t do it because the sun was not shining.
