Chapter 12.7, Problem 2P

Suppose that you have a map on which 1 inch represents 25 miles. You cover a county on the map with a $\frac{1}{8}$ -inch-thick layer of modeling dough. Then you re-form this piece of modeling dough into a $\frac{1}{8}$ -inch-thick rectangle. The rectangle is $1\frac{3}{4}$ inches by $2\frac{1}{4}$ inches. Approximately what is the area of the county? Explain.
