A certain forest covers an area of 2900 km. Suppose that each year this area decreases by 3.25%. What will the area be after 7 years?
Use the calculator provided and round your answer to the nearest square kilometer.

i got 10.28 but that rounds up to 10.3

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
