Question

Kerry skates laps around the playground.

Answer 1

So to start this off, we need to find the area of the playground. We can simply multiply 150*2 and 50*2, and we get 300 and 100. Add those together and we get 400m.
Now, we can identify the number of laps it takes. But first, we have to convert kilometers into meters. there are 1000 meters in 1 km, so we will use 1000 to find the answer
Now, we can do 1000/400 to find the answer, which is 2.5 
Therefore, it will take Kerry 2.5 laps to skate around the entire park

Answer: 2.5 laps

Hope this helped!!! :D
