As one does not actually reach the limit, one is not actually dividing by zero until one reaches the limit. Instead, one is dividing seven by an increasingly smaller number; ergo, the limit is infinity.
I think you need more homework. Here are some word problems for you to brush up:
A rectangular swimming pool measures 20 meters by 10 meters. How wide must a concrete walk around the pool be if the walk is to cover an area of 124 square meters?
A man wants to build a rectangular enclosure for his herd. He only has $900 to spend on the fence and wants the largest size for his money. He plans to build the pen along the river on his property, so he does not have to put a fence on that side. The side of the fence parallel to the fence will cost $5 per foot to build, whereas the sides perpendicular to the river will cost $3 per foot.What dimensions should he choose?
