Iwant to fence in a square vegetable patch. the fencing for the east and west sides costs $7 per foot, and the fencing for the north and south sides costs only $5 per foot. find the total cost of the fencing as a function of the length of a side x (feet).

The square has 4 sides: the north, south, east and west ones. Each side is x feet long, because the side of a square are all equal in length. We know the cost per foot for each side:

The total cost of the fence is the sum of the costs of the sides, so we have

So, if each side is x feet long, the fence will cost 24 times the length of each side.
