4.4+Using+Map+Scales

=__Problem 4.4 Aiman Q.__= __**A. How can use the scale on the map to calculate the scale factor between the map and the real state? What is the scale factor?**__
 * Block B**
 * 12 - 8 - 08**

Answer: You can the scale on the map to calculate the map and the real state by measuring the scale. **(2cm= 100km)** Then I did 2cm= 100km 2cm= 10000cm<--divide by 2. 1cm: 500cm<--SF.**
 * 2cm= X cm

__**B. How many miles of fencing would it take to surround the state of Utah?**__

10.8+8.6+8.7+3.2+2.2+4.3= 37.8 X 50= 1,800km. It will take **1,800km** of fencing to surround the state of Utah.

__**C. Use the scale to estimate the area of Utah. Explain your work.**__

Measure the width and length of the area of the area of Utah, and then convert it to km by multiplying it by 50. Then do 430km X 430km= 184,900km. That’s for the area of the whole rectangle. To find the area of the indent to subtract it, you need to measure the side lengths. Then do 110km X 160km= 17600km. Then subtract 17600km from184, 900km to get the area of Utah.

__**Area of Utah---167, 300km.**__

__**D. If you drove at a steady speed of 55miles per hour, about how long would it take you to travel from Logan to Saint George?**__

It will take me **5.81818181** hours, or around 6 hours if rounded.

=**__Problem 4.4 Follow Up.__**=

__**1. The total land and water area of the United States is about 3,717,522 square miles. What percent of this total area is the area of Utah?**__

Area of Utah--- 167,300 square miles. Area of United States--- 3,717,522 square miles.

3,717,522/167,300= 0.0450031 X 100= 4.50%

__**Answer: 4.50%**__
