Perimeter and area are not sufficient to determine the shape of a figure.

If the figure is a square or rhombus (and why should that be?) the perimeter would be 20 cm = 0.2 metres
40
It depends on the configuration of the 100 squares. Different configurations - 1*100 or 2*50 etc will give different perimeters.

That's because "perimeter" means the distance around something - not the spaces inside. If you count squares inside a figure, you are finding the AREA, not the PERIMETER.
P = 20 cm
It could be: 4n = 20 and so n = 5 feet

Yes
the perimeter of a rectangle with two 5cm squares will be 30cm
