Perimeter and area are not sufficient to determine the shape of a figure.
a rectangle
Yes
Yes.
The perimeter is 8 + 5 + 2 + 3 = 18 inches. The area is indeterminate since the sides of a four sided figure do not uniquely determine its shape - it is flexible in the same way that a square can be flexed into a rhombus and the area reduced to zero.

It depends. What shape is it? And is it equilateral or not?
Yes if you

a 4*5 rectangle.
Actually it is possible.
The simplest shape is a 6ft*3 ft rectangle.
No, the size of the perimeter and the area of a shape are not always directly related. For example, a circle with a small perimeter can have a larger area compared to a square with a larger perimeter. The area of a shape is determined by the size of its dimensions, whereas the perimeter is the sum of the lengths of its sides.
