The area of a rectangle is not sufficient to determine its shape and therefore its perimeter.
For example, each of the following rectangles has an area of 22 square units. But the perimeter, P, varies considerably.
sqrt(22)*sqrt(22) : P = 4*sqrt(22)
2*11 : P = 26
1*22 : P = 46
0.1*220 : P = 440.2
0.01*2200 : P = 4400.02
0.001*22000 : P = 44000.002
As you may begin to see, there is no limit to the perimeter.

Yes. For instance, the rectangle measuring 1 by 10 has a perimeter of 22 and an area of 10, whereas the rectangle measuring 4 by 4 has a perimeter of 16 and an area of 16.
That depends on the dimensions !... A 1 x 18 rectangle has a perimeter of 38 ! A 2 x 9 rectangle has a perimeter of 22 ! A 3 x 6 rectangle has a perimeter of 18 !
A square of side 22 has an area of 484. Rectangle 23 x 21 has an area of 483...

A 3 x 8 rectangle
the area of a rectangleis 100 square inches. The perimeter of the rectangle is 40 inches. A second rectangle has the same area but a different perimeter. Is the secind rectangle a square? Explain why or why not.
No. For example, a 4x1 rectangle will have an area of 4 and a perimeter of 10. A 2x2 rectangle will have the same area of 4, but a perimeter of 8.
The length of a rectangle is twice its width. If the perimeter of the rectangle is , find its area.
