Answer:
I believe its 8624.03
Step-by-step explanation:

Believe it or not, :), the width of the ribbon needs to be known to get the right answer. If the ribbon had an infinitely small width the ribbon needed would just be the perimeter.
P=2(L+W)
P=2(12+15)
P=54 in
However an infinitely small width is not something that has any practical application. For example, if the width of the ribbon were 1/2 in.
P=2((L+1)+W)
P=2(16+12)
P=56 in So the perimeter increased by 2 in when the ribbon was only 1/2 in wide.
The "infinitely small" width and the perimeter of 54 in is only a decent approximation if the ribbon were a very thin string.
Answer:
should be (4a-5)x(4a+5)
Step-by-step explanation:
A. A 25-word classified ad would cost $17.50
Explanation: 0.55 x 10 = 5.5. 5.5 + 12 = 17.5
B. A 50-word classified ad would cost $31.25
Explanation: 0.55 x 35 = 19.25. 19.25 + 12 = 31.25
