The formula to calculate the number of posts is:

\[ \text{Number of Posts} = \left\lceil \frac{\text{Fence Length (ft)}}{\text{Single Fence Length (ft)}} \right\rceil + 1 \]

The formula to calculate the number of fence panels is:

\[ \text{Fence Panels} = \left\lceil \frac{\text{Fence Height (ft)} \times 12 - \text{Top Panel Distance (in)} - \text{Bottom Panel Distance (in)}}{\text{Panel Height (in)}} \times (\text{Number of Posts} - 1) \right\rceil \]
