First of all, the area cannot be 40 cm since an area is 2-dimensional whereas the measure given is 1-dimensional. Next, the shape is not defined and so the width, length and perimeter are indeterminate.
Even if you assume that the shape is a rectangle, the width, length and perimeter are indeterminate. On the basis that the length is greater than the width, all that you can say is that the length will be greater than or equal to sqrt(40) = 6.324555 (to 6 dp), the width will be 40 divided by that length and the perimeter will be twice their sum.
Some examples:
Length = 8, width = 5, perimeter = 26
Length = 10, width = 4, perimeter = 28
Length = 40, width = 1, perimeter = 82
Length = 4000, width = 0.01, perimeter = 8000.02
Length = 4,000,000, width = 0.00001, perimeter = 8,000,000.00002
and so on, without limit.

you need length and width length multiply width = area length + length + width + width = perimeter
The perimeter is equal to length + length + width + width while area is length x width. Both measurements are found by using width and length.
Area = Length*Width so Width = Area/Length. Therefore the Width can be calculated. Then, perimeter = 2*(Length + Width) and everything on the right hand side of the equation is known so the perimeter can be calculated.
Area = Legth x Width In a square, Length = Width Therefore Area = Length x Length (or Width x Width) Area = Length squared Length = Square Root of 800 Perimeter = 4 x length Perimeter = 4 x Square Root of 800 Perimeter = 113.14
perimeter is the measure around the figure; area is the measure within the figure formula: perimeter: length+length+width+width=perimeter (for square or rectangle) area: length times width= area ( for square or rectangle)
