So to find the perimeter of a square, we must add all of the sides together.
We know that a square's sides are all equal in length and that a square has 4 sides. So that means we need to add 4.7 four times to get the perimeter.
4.7 + 4.7 + 4.7 + 4.7 = 18.8
So the perimeter of the square is 18.8 cm.

Answer:
20 chairs
Step-by-step explanation:
Since we are given the amount total budget and the total amount for the desks then the only variable missing is the maximum amount of chairs. This can be solved with the following equation in which s represents the number of chairs, and we simply solve for s.
800 = 320 + 24s ... subtract both sides by 300
500 = 24s ... divide both sides by 24
20.83 = s
Now we see that the maximum number of chairs that the librarian can buy is 20 because 21 would make her go over the budget and you cannot have 0.83 of a chair.
