Any length you like.
8 metres? The width is 8000/800 = 10 cm
8 kilometres? The width is 8000/800,000 = 0.01 cm = 100 micrometres
8,000 kilometres? The width is 100 nanometres.
and so on.
To find the length of the sides of a square given its area, you take the square root of the area. In this case, the area is 25 square centimeters. The square root of 25 is 5, so each side of the square is 5 centimeters long.

The area of rectangle is : 100.0
If the area of a square is 1 square meter, then there is one meter on each side. Since there are 100 centimeters in a meter, then there are 100 centimeters on each side.
Each side of the square would be 6 centimeters, becasue the area is 6 x 6 = 36 cm. So the perimeter of the square is 6 cm x 4 sides = 24 cm long.
If it is 4.68 cm long by 2.01 cm wide, then the area is 4.68 x 2.01 = 9.41 square centimeters.
Each side is 20 cm
