Answer:
A
Step-by-step explanation:
1/9 acres. It's 9lbs/acre so you dive that by 9 and get 1/9 acres/lbs.
LW = 45
L + 2W = 19
L = 19-2W
substituting for L :-
W(19-2W) = 45
-2W^2 + 19W = 45
2W^2 - 19W + 45 = 0
W = 5 or 4.5
If W = 5, L = 9
If W = 4.5, L = 10
So there are 2 possible answers.
The answer to your problem is 69
