Answer:
![Area = 81cm^2](https://tex.z-dn.net/?f=Area%20%3D%2081cm%5E2)
Step-by-step explanation:
Given
![Length = 12](https://tex.z-dn.net/?f=Length%20%3D%2012)
![Width = 6cm](https://tex.z-dn.net/?f=Width%20%3D%206cm)

Determine the area of a square with the same perimeter
First, calculate the perimeter (P) of the rectangle.
![P=2*(Length + Width)](https://tex.z-dn.net/?f=P%3D2%2A%28Length%20%2B%20Width%29)
![P=2*(12 + 6)](https://tex.z-dn.net/?f=P%3D2%2A%2812%20%2B%206%29)
![P=2*18](https://tex.z-dn.net/?f=P%3D2%2A18)
![P=36](https://tex.z-dn.net/?f=P%3D36)
The perimeter of a square is:
![P = 4L](https://tex.z-dn.net/?f=P%20%3D%204L)
Where L is the side length.
Substitute 36 for P
![36 = 4L](https://tex.z-dn.net/?f=36%20%3D%204L)
Make L the subject
![L =\frac{36}{4}](https://tex.z-dn.net/?f=L%20%3D%5Cfrac%7B36%7D%7B4%7D)
![L =9](https://tex.z-dn.net/?f=L%20%3D9)
The area of the square is:
![Area = L^2](https://tex.z-dn.net/?f=Area%20%3D%20L%5E2)
![Area = 9^2](https://tex.z-dn.net/?f=Area%20%3D%209%5E2)
![Area = 81cm^2](https://tex.z-dn.net/?f=Area%20%3D%2081cm%5E2)

Answer:
![x](https://tex.z-dn.net/?f=x%3C%5Cfrac%7By%2B8%7D%7B4%7D)
![x\geq \frac{y}{4} -1](https://tex.z-dn.net/?f=x%5Cgeq%20%5Cfrac%7By%7D%7B4%7D%20-1)
Step-by-step explanation:
no the answers aren't the same
8² = 64
-1³ = -1
2×2×2×2×2 = 32
64 × -1 = -64
-64 ÷ 32 = -2
I believe the answer is 15in because the formula for circumference is pie× diameter and then you divide 47.1 by 3.14 or pie and you get 15 in. I Hope this helps you!! :)
