The area of a forest is three times the area of the square-shaped street. If the street has a length of 100 meters on one side and the number of trees per square meter in the forest is 4, calculate the total number of trees in the forest. Let's think step by step and output the final answer after "####".

Since the area of a square is sides squared, the area of the square-shaped street is 100*100 = <<100*100=10000>>10000 square meters.
The area of the forest is three times the area of the square-shaped street, a total of 3*10000 = <<3*10000=30000>>30000 square meters.
If the number of trees per square meter in the forest is 4, there are 4*30000 = <<4*30000=120000>>120000 trees in the forest.
#### 120000
