If the perimeter of a square is 12 inches wouldn't you just add 12+12+12+12 and get 48?
It depends upon the question. If the PERIMETER of a square is 12 inches, then each SIDE must be 12/4 = 3 inches. If each SIDE of the square is 12 inches, then the perimeter is 48 inches.
That's what I thought too but the choices that I have are
A. 3 in. 2
B 9 in.2
C. 16 in.2
D. 144in.2
What you wrote first was not a question. Please post the question as it is written.
from the little 2 you have at the end of each possible answer, I conclude that you meant "in^2" or square inches.
So the question deals with "area", and probably said ...
If the perimeter of a square is 12 inches, what is its area?
As DrBob already told you, each side must be 3 inches and then the area would be 9 square inches
which looks like your choice B
Yes, you are correct! To find the perimeter of a square, you add the lengths of all four sides. Since all sides of a square are equal in length, you can multiply the length of one side by 4 to get the perimeter.
So, if the perimeter of the square is given as 12 inches, you can add 12 + 12 + 12 + 12 to get a total of 48 inches.
