Final answer:
Without additional information such as the length or a relationship between the length and width of the rectangle, it's not possible to determine the width from the perimeter alone. Moreover, the detail about a building with actual dimensions of 140 ft by 100 feet cannot be verified to be related to the question at hand.
Step-by-step explanation:
The student asks to determine the actual width of the rectangle when given the perimeter.
To find the width of the rectangle, we need to know both the perimeter and either the width or the length of the rectangle.
Unfortunately, without additional information such as the length or a relationship between the length and width, it's not possible to determine the width solely from the perimeter.
All other options (A, B, and D) suggest formulas or fixed numbers that cannot be evaluated without more data.
Since the perimeter is given as 436 feet, and we know the perimeter of a rectangle is calculated by P = 2l + 2w, where P is the perimeter, l is the length, and w is the width, we would need one more piece of information to solve for the width.
However, among the multiple choices given by the user, only choice C gives an actual number, which is 108 feet for the width.
If this were the actual width of the rectangle, the length could be calculated correspondingly given the perimeter. But this width cannot be confirmed as correct without more information or context from the question.
In the context provided, where the actual dimensions of a building are given as 140 ft by 100 feet, if this were the same rectangle, then the width would be 100 feet and not 108 feet as option C suggests.
In reality, without the additional needed information, we cannot confirm the actual width.
