Answer 1

The correct option is A $1365$

Trees planted in 1 day $=65$ trees

1 Week has 7 days.
So, Total number of tress planted in 3 weeks $=65\times 3\times 7$
Using associative law of multiplication:
$65\times 3\times 7=65\times (3\times 7)=65\times 21$


So, In three weeks 1365 trees can be planted.
