Evaluate the function to answer the question.
Botanists have determined that some species of weed grow in a circular pattern. For one such species, the area A, in square meters, can be approximated by A(t) = 0.0067nt^2, where t is the time in days after the growth of the weed first can be observed. Find the area (in square meters) this weed will cover 100 days after the growth is first observed. Round to the nearest square meter.
