Its area is: 8 times 8 = 64 square centimetres
A square with 6 metres sides would have an area of 6 metres x 6 metres which is 36 square metres.
It is 36 feet. 36 sqare feet
If one of the sides is 8 feet, the perimeter is 32 feet and the area is 64 square feet.

A two metre square is a square with sides of two metres. This would have an area of 4 square metres. 2 square metres is the area of square with sides sqrt(2).
It is a square area with sides of 80 metres.

The total area of Vietnam is 331,210 square (not sqare) km.
I'm not sure what you mean but try this. If a rectangle has sides of 4 metres and 3 metres then the area of the square is 12 square metres
If 23 of the area of the square is 54 then the area of the whole square is 54/23 = 2.3478 square metres. The sides are, therefore, 1.5323 metres and so the perimeter is 6.1290 metres.
Each side = 8 metres (32 divided by 4 sides). The area = 8 x 8 = 64 square metres.
