Runners race around a rectangular park during the city marathon. The length of the park is 6 miles. The width of the park is 7 miles. Which is the correct unit of measurement to use when figuring out how many miles someone would run during the marathon? A. miles3 B. miles C. miles2

Answer=B

The question asks us to the miles someone would run during the marathon. Since, the marathon goes around the park, the question is asking for the perimeter of the rectangular park. The perimeter for a rectangle is:

P=2 (l+w)

P=2l+2w

The ending unit of measurement would be miles.

P=2 (6+7)

P=2 (13)

P=26 miles
