First term, a=1

Common difference, d=2−1=1

S

n

n

[2a+(n−1)d]

S

12

=

12

[2(1)+(12−1)(1)]

=6(2+11)

=6(13)

=78

Therefore, number of trees planted by 1 section of the classes =78

Number of trees planted by 3 sections of the classes = 3×78=234

Therefore, 234 trees will be planted by the students.
