Sometimes calculating a business profit requires using a quadratic function. Think about how the problems presented below might involve a quadratic and how it could involve a business calculation. People frequently need to calculate the area of rooms, boxes or plots of land. An example might involve building a rectangular lawn or room where one side must be twice or three times the length of the other side. For example, if you have to paint the room or lay down wood on the floor of the room or do some other work, with this information, you can create an equation for the area of the room using the ratio of the two sides. Provide some examples or work you would do and what type of business calculation. How would set up the equation for this problem?
