No, He needs to to mow 7 more lawns before he has mowed 29 lawns.

Step-by-step explanation:

Given: The number of lawns by Samuel in each month =- 3

The number of months he mowed the lawns = 7

Then, the number of lawns mowed by Samuel = $7\times3=21$

Let x be the number of lawns he needs to mow before he has mowed 29 lawns, then x<29

The number just before 29 is 28

Then, $x=28-21\\\Rightarrow\ x=7$

Hence, he needs to to mow 7 more lawns before he has mowed 29 lawns.
