Since the cost of seeding the field is proportional to the area of the field. Then we could calculate the cost of seeding the larger field by scaling up the cost of seeding the smaller field.

The area of the larger field is (4.5)(4.5) = 20.25 times the area of the smaller field, and so the cost of feeding should be 20.25 times.

Therefore, cost = 20.25(176) = $3564.
