Final answer:
To find the length of the rectangle, divide the area by the width. The length can be up to 160 feet.
Step-by-step explanation:
To find the length of the rectangle, we can use the formula for the area of a rectangle, which is length multiplied by width. We know that the width of the rectangle is 125 feet, and the area should not exceed 20,000 square feet. So we can set up the equation: length * 125 = 20,000.
To solve for the length, we divide both sides of the equation by 125: length = 20,000 / 125 = 160 feet.
Therefore, the length of the rectangle can be up to 160 feet.
