A group of students were allotted a quadrilateral patch in the school campus to make a garden. They cleared up the patch and decided to grow medicinal plants. Find the area of the patch, if the dimensions are as given in the figure.

The equation above can be used to model the population, in thousands, of a certain city t years after 2000. According to the model, the population is predicted to increase by 0.5% every n months. What is the value of n?

Note:
We need to understand what each quantity given in the equation 
represents. For example, the population in year 2000 is 2,15,000. After 3 tears, that is, in year 2003, the population becomes  thousand which is 216075.
