The given answer consists of three options: 22.45 cm, 22.45 centimeters, and 22.45. These options all represent the same length measurement, which is 22.45 units. The use of both "cm" and "centimeters" indicates that the measurement is in centimeters, and the numerical value of 22.45 represents the length itself.Rate this question:

3-21. Stacy exercises three days each week by walking around the soccer field near her home. The field is 80 yards wide and 115 yards long.1. Draw a diagram of the field. Then find how far Stacy walks in one trip around the field. This distance is called the perimeter.
Explanation
Stacy walks around the soccer field, which has a width of 80 yards and a length of 115 yards. To find the perimeter, we add up the lengths of all four sides of the field. The two shorter sides have a length of 80 yards each, and the two longer sides have a length of 115 yards each. Adding these lengths together, we get 80 + 80 + 115 + 115 = 390 yards. Therefore, Stacy walks a distance of 390 yards in one trip around the field.Rate this question:

3-21. Stacy exercises three days each week by walking around the soccer field near her home. The field is 80 yards wide and 115 yards long. (Use your answer from the last question to help you solve this one.)2. If Stacy walks around the field four times each time she exercises, how far does she walk each week?
Explanation
Stacy walks around the field four times each time she exercises. The field is 80 yards wide and 115 yards long. To calculate the distance she walks each time, we add the length of all four sides of the field. The perimeter of the field is 2 times the sum of the width and length, which is 2(80 + 115) = 2(195) = 390 yards. Since Stacy walks around the field four times, the total distance she walks each time she exercises is 4 times the perimeter, which is 4(390) = 1560 yards. Therefore, she walks a total of 1560 yards each week.Rate this question:
