Question 790604: "The martins own a forestry field. They have grown each tree from seedlings to be harvested after a 10-year period. The field contains 152 trees. The number of trees in each row is 3 more than twice the number of rows. Find the number of rows and the number of trees per row".
Can I get help with setting up and solving this word problem?
I feel that the "10-year period" part is unneeded information and does not go into the equation, but I am not sure on this.
Thank you for your time!

The martins own a forestry field. They have grown each tree from seedlings to be harvested after a 10-year period.
The field contains 152 trees. The number of trees in each row is 3 more than twice the number of rows. Find the number of rows and the number of trees per row.
--------------
Let # of rows be "r".
# of trees in each row = 2r+3
--------
# of trees = r(2r+3) = 152
-----
2r^2 + 3r - 152 = 0
-----
r = 81
------------
