Final answer:
The question involves using a quadratic function to model the area of a rectangle with a given perimeter. The function is not applicable to a width of 100 feet since it exceeds the logical constraints of the rectangle's perimeter.
Step-by-step explanation:
The student is asking about determining the dimensions of a rectangular area given a fixed perimeter and using a function to find the area for a given width, w. The function provided, A(w)=24w−w^2, is a quadratic function that models the area of a rectangle with a fixed perimeter of 144 feet. When the width is defined as w=100 feet, we cannot use this particular function to find the area because it would imply an unrealistic negative length for the remaining side, given the fixed perimeter constraint. Therefore, the function can only model the situation over the interval where 0 < w < 24, as the width must be less than half of the perimeter for a rectangle.
