Chapter 11.7, Problem 9WE

To determine

To Find: The ratio of map area to the actual area of the California.

Answer to Problem 9WE

  $1:25,000,000,000,000$

Explanation of Solution

Given: On a map of california $1cm$ corresponds to $50km$ .

Converting kilometers into centimeters.

  $50km=50(100,000)=5,000,000cm$

Given that $1cm$ corresponds to $50km$ .

i.e.

Scale factor is a $1:5,000,000$

Now ratio of areas.

  $\begin{array}{l}$ 1^2:{(5,000,000)}^2$=1:25,000,000,000,000\end{array}$
