A foresty sevice biologist has time to study insect infestation in an area of 50 kilometers. On the forest service map, the scale is 1 centimeter equals 1 kilometer. The four possible sectors available for study appear as rectangles on the map. Complete the table by calculating the map area of each sector.

How can you calculate the actual area of each sector?

Does the biologist have time to study all four areas? explain why or why not?

What combinations of three sectors could the scientist study?

Which combination of sectors maximizes the area to be studied?
Explain why.
