To determine the cost of the wood fencing for enclosing the rectangular field, we first need to calculate the perimeter of the rectangle.
The perimeter \( P \) of a rectangle can be calculated using the formula:
\[
P = 2 \times (length + width)
\]
For the dimensions given:
- Length = 158 yards
- Width = 47 yards
Calculating the perimeter:
\[
P = 2 \times (158 + 47) = 2 \times 205 = 410 \text{ yards}
\]
Next, we convert the perimeter from yards to feet because the cost of the fencing is given in per foot. There are 3 feet in a yard, so:
\[
P = 410 \text{ yards} \times 3 \text{ feet/yard} = 1230 \text{ feet}
\]
Now, we calculate the total cost of the wood fencing by multiplying the total length of the fencing required by the cost per foot:
\[
\text{Cost} = \text{Length in feet} \times \text{Cost per foot}
\]
Substituting the values:
\[
\text{Cost} = 1230 \text{ feet} \times 3.28 \text{ dollars/foot} = 4034.40 \text{ dollars}
\]
Thus, the total cost of the wood fencing is:
\[
\text{Cost} = 4034.40
\]
So, the correct answer is:
**D. $4,034.40**
