Answer:
Step-by-step explanation:
At most, the area is 140 ---> the area is (3x + 2)10
So, as an inequality, you get (3x + 2) 10 ≤ 140
Simplify
30x + 20 ≤ 140
30x ≤ 120
x ≤ 4
Can 3x + 2 be 15?
Plug in the greatest value of x, and get 3*4 + 2, which is 12 + 2, which is 14
No, at most the length can be 14, which is less than 15.
