Answer 2

Answer:

640cm²

Step-by-step explanation:

Perimeter = length of one side x 4 ( sum of all the 4 sides)

       320  = y x 4 ( taking the length of a side as y

        320 = 4y

     320/4 = 4y/4

          80 = y

The length of one side is 80m

Then,

Area = length x breadth

Since length and breadth of a square are equal,

Area = y x y

        = 80 x 80

        = 640cm²
