To determine the number of fence posts needed around a rectangular field of dimensions 300 feet by 150 feet with fence posts placed every 25 feet, we first need to calculate the perimeter of the field.
1. **Calculate the perimeter of the rectangular field**:
\[
\text{Perimeter} = 2 \times (\text{Length} + \text{Width}) = 2 \times (300\, \text{ft} + 150\, \text{ft}) = 2 \times 450\, \text{ft} = 900\, \text{ft}
\]
2. **Determine the number of sections between the fence posts**:
The posts are placed every 25 feet. To find the number of posts required, we divide the perimeter by the spacing:
\[
\text{Number of sections} = \frac{\text{Perimeter}}{\text{Spacing}} = \frac{900\, \text{ft}}{25\, \text{ft}} = 36
\]
3. **Calculate the total number of fence posts**:
Since we need one more post than the number of sections to enclose the field, we add 1 to the number of sections:
\[
\text{Total number of posts} = \text{Number of sections} + 1 = 36 + 1 = 37
\]
Thus, **37 fence posts** are needed to enclose the 300x150 ft rectangular field at 25 ft spacing.
