How more feet is the outer perimeter of the walkway than the perimeter of the pool is  48 ft
Since 6ft is the width of walkaway
Hence:
Let increase in width  be 12
Let increase in length  be  12
Now let determine How many
more feet is the outer perimeter of the walkway than the perimeter of the pool
Outer perimeter Number of feets  = 2×(12+12)
Outer perimeter Number of feets  = 2×24
Outer perimeter Number of feets  = 48 ft
Inconclusion How more feet is the outer perimeter of the walkway than the perimeter of the pool is  48 ft

Answer:
Cluster sample
Step-by-step explanation:
This is an example of a cluster sample. In a cluster sample, the examiner divides the population into groups (each one of these groups is called a cluster) and once the examiner has these clusters, takes one of them and recollects the data from ALL the members of that cluster. In this case, the teacher divided the class in 3 different groups and then selects one of these groups and asks the average amount of time per week he/she spent studying.
