Avery is building a playground. There are 9 different slides and 4 swing sets to choose from. If the playground will include one of each type of play structure, how many different playgrounds can Avery build?
To find the total number of different playgrounds Avery can build, we need to multiply the number of choices for each type of play structure.
Total number of playgrounds = Number of slides * Number of swing sets
Total number of playgrounds = 9 slides * 4 swing sets
Total number of playgrounds = 36
Avery can build 36 different playgrounds.
