it is an unasewrd question you see this is so hard that my grand daughter couldnt figure it out. so give up and good luck
Perimeter and area are not sufficient to determine the shape of a figure.
20 cm
20 cm
Yes
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.

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