Answer:
Step-by-step explanation:
Expression for the rectangular area and perimeter are, respectively:
After some algebraic manipulation, area expression can be reduce to an one-variable form:
The first derivative of the previous equation is:
Let the expression be equalized to zero:
The second derivative is:
According to the Second Derivative Test, the critical value found in previous steps is a maximum. Then:
The maximum area is:
2p^2 + 30p + 108 2(p + 6)(p + 9)
----------------------- = -------------------- = 2(p + 9) / (p - 1)
p^2 + 5p - 6 (p + 6)(p - 1)
Its the first choice
Yes
