Total 7*10^5 trees were planted.
Further explanation:
The product of both quantities will give us the total number of trees planted by the students for the community project.
So,
Given
[tex]Trees\ planted\ by\ each\ student=2*10^2\\Total\ students\ in\ school=3.5*10^3\\Total\ trees\ planted= (2*10^2)*(3.5*10^3)\\= 7*10^5\ trees[/tex]
So, total 7*10^5 trees were planted.
