4-4 Solve. GEOMETRY Each side of polygon ABCD is 5 times as long as the corresponding side of polygon FGHI. Find the perimeter of polygon ABCD. Lesson 4-4 Example 4

4-4 Understand Read the problem. Write what you know. Each side of polygon ABCD is 5 times as long as the corresponding side of polygon FGHI. Lesson 4-4 Example 4

4-4 Plan Pick a strategy. One strategy is to make a table showing the corresponding sides. Lesson 4-4 Example 4

4-4 Solve First, fill in the corresponding sides of polygons FGHI and ABCD. Then fill in the measurements of the sides of polygon FGHI. All measurements are in inches. Multiply the length of each side of polygon FGHI by 5 to find the lengths of the sides of polygon ABCD. Complete the table. Lesson 4-4 Example 4

4-4 The perimeter is the sum of the lengths of the sides. What is the perimeter polygon ABCD? 85 inches Lesson 4-4 Example 4

4-4 Check Does the answer make sense? Look over your solution. Did you answer the question? Lesson 4-4 Example 4
