A rectangular park is 150 yards on one side and 125 yards on the other. if Debbie walks around the park two times, how far does she walk

Well seeing as how its around the park we think perimeter.

P = 2L + 2W

P = 2 (150) + 2 (125)

P = 300 + 250

P = 550

so we know the perimeter of the park is 550 yards but she walks this perimeter twice so 550*2 gives you 1100 yards that she walked.
