Final answer:
The amount of fencing Marie needs depends on the dimensions of her yard, so we cannot determine the exact answer without more information.
Step-by-step explanation:
To determine how many feet of fencing Marie needs for her yard, we need to know the dimensions of her yard. The question does not provide any specific dimensions, so we cannot calculate the exact answer. However, we can note that the options given indicate different lengths of fencing, ranging from 13 feet to 104 feet. Therefore, we can conclude that Marie needs a variable amount of fencing depending on the size of her yard, and the correct answer will depend on the specific dimensions of her yard.
