To find the width of the rectangle, you can use the formula for the area of a rectangle:
\[ \text{Area} = \text{length} \times \text{width} \]
Given that the area is 375 square feet and the length is 25 feet, you can rearrange the formula to solve for the width:
\[ \text{width} = \frac{\text{Area}}{\text{length}} \]
Substituting in the values:
\[ \text{width} = \frac{375 , \text{ft}^2}{25 , \text{ft}} \]
Calculating this gives:
\[ \text{width} = 15 , \text{ft} \]
So, the width of the rectangle is 15 feet.
