The street is 40 meters long.
We will count the trees from the beginning of the street to the end.
There are two trees on the beginning of the street==> 2 trees
After 10 meters, there are two more trees ==> 2 trees
After 20 meter, there are two more trees ==> 2 trees
After 30 meters, there are two more trees ==> 2 trees
After 40 meters, there are two more trees==> 2 trees
Now counting all trees we have : 2 + 2 + 2 + 2+ 2 = 10 trees.
Then, the total number of trees lining the street is 10 trees.
