It seems like you're describing the dimensions of a rectangular yard, which are 78 feet in length and 64 feet in width. Could you clarify what you'd like to do with this information? Are you looking to calculate the area, perimeter, or something else?

If you're looking for the area, here's how you can calculate it: $\text{Area} = \text{Length} \times \text{Width} = 78 \, \text{ft} \times 64 \, \text{ft} = 4992 \, \text{square feet}$

Let me know if you'd like to explore something else!
