Let the side of one square be x and the other square be y.
Formula of perimeter of a square:
4×side
So,the perimeters of the both the squares 4x and 4y.
According to the given condition,
4x-4y=64
=>4(x-y)=64
=>x-y=16
=>x=16+y
=>y=x-16...............[1]
Now,
Given that the areas of the squares have a difference of 640m^2.
Area of a square:
side×side=side^2
Hence,
Using [1],
Putting x=32 in [1],
Hence,(x,y)=(28,12)
