Some students have a map with a scale of 1 inch30 miles. A county on the map has been traced onto inch graph paper. (The grid lines are spaced inch apart.) The students agree that the county takes up about 55 squares of graplh paper. The students have several initial ideas and unfinished calculations for determining the area of the county. For each of these initial calculations, either use them to finish determining the area of the county or explain why they will probably lead to an error.
