A = s2 (Area of a square is its side squared)
P = 4s (perimeter of a square is a side times 4)
A = 324 (the area of this square is 324 ft2)
fencing = $7 per foot
Let's find the side through the area. Find the root:
√324 = √s2
18 = s
Now the perimeter:
P = 4 * 18 = 72
Now to find how much the fencing will cost:
72 * 7 = 504
The answer simplified is 12r-20
Answer:
3
Step-by-step explanation:
If there are 12 per bag then you would multiply the number of bags by the number of apples. In this case 12*2=24 he needs 30 so, 12*3=36 if he gets 3 bags he will have enough for one week and still have 6 left over.

18 books in 7th grade.
% Change = (18 - 15) /15 * 100%
= 3/15 * 100%
= 1/5 * 100% = 20%
Percent change = 20%.
