2 one do you need explanation ??
Answer:
10 adults
Step-by-step explanation:
1 adult per 6 children
there already 1 adult per class so 6 children from each class are covered
24 - 6 = 18
26 - 6 =20
28 - 6 = 22
18 + 20 + 22 = 60
60 ÷ 6 = 10
so 10 more adults are needed
Because it is a square all sides are equal so all sides are 20.25 because half of 81 is 40.5 and half of that is 20.25.
