dont know dont care
You can't tell the linear dimensions from knowing only the area. There are an infinite number of shapes that all have the same area. Even if you consider only rectangles, there are still an infinite number of different rectangles, all with different lengths and widths, that all have areas of 5,000 acres.
The equation for the perimeter of a rectangle is 2(a+b) where a is the length of the short side and b is the length of the long side. In this case 2(a+b)=18, so a+b=9 keeping in mind that a has to be shorter than b (to be the short side), the possible answers to this are: a=1, b=8 a=2, b=7 a=3, b=6 a=4, b=5
You can't tell the perimeter from the area. There are an infinite number of different shapes,all with different perimeters, that have the same area. Even if you only consider rectangles,there are still an infinite number of those that all have the same area and different perimeters.Here are a few rectangles with area of 6 square feet:Dimensions ... Perimeter0.75 x 8 . . . . . . 17.51 x 6 . . . . . . . . 141.5 x 4 . . .. . . . 112 x 3 . . . . . . . . 10
There would be an infinite number of rectangles possible
There is no relationship between the perimeter and area of a rectangle. Knowing the perimeter, it's not possible to find the area. If you pick a number for the perimeter, there are an infinite number of rectangles with different areas that all have that perimeter. Knowing the area, it's not possible to find the perimeter. If you pick a number for the area, there are an infinite number of rectangles with different perimeters that all have that area.

There is an infinite number that can have that perimeter
perimeter = 2 (b+h) = 20 there are an infinite number of rectangles that meet the requirement
Infinite in number, from a 4 x 4 square to 0.0000001 x 7.9999999 etc
There are infinitely many possible rectangles. Let A be ANY number in the range (0,6] and let B = 12-A. Then a rectangle with width A and length B will have a perimeter of 2*(A+B) = 2*12 = 24 units. Since A is ANY number in the interval (0,6], there are infinitely many possible values for A and so infinitely many answers to the question.
To be perfectly correct about it, a perimeter and an area can never be equal.A perimeter has linear units, while an area has square units.You probably mean that the perimeter and the area are the same number,regardless of the units.It's not possible to list all of the rectangles whose perimeter and area are thesame number, because there are an infinite number of such rectangles.-- Pick any number you want for the length of your rectangle.-- Then make the width equal to (double the length) divided by (the length minus 2).The number of linear units around the perimeter, and the number of square unitsin the area, are now the same number.
You can't tell the dimensions from the perimeter. There are an infinite number of different rectangles, all with different lengths and widths, that all have the same perimeter.
1 x 8 2 x 7 3 x 6 4 x 5
The number of such rectangles is always infinite.Select any length, B such that 0 < B ≤ P/2 units of length and let L = P/2 - B.Then a LxB rectangle has perimeter 2*(L+B) = 2*(P/2 - B + B) = 2*(P/2) = P.B was chosen arbitrarily from an infinite number of possible values and so there are infinitely many possible solutions.See discussion section for further thoughts.
There are an infinite number of rectangles with this perimeter. The "whole number" sides could be (5 x 1), (4 x 2) or (3 x 3), but (5½ x ½) or (3¼ x 2¾) etc would fit the description.
