Expert Answer
Let the sides of the 2 squares be x and y.
Then x2 + y2 = 640.....(i)
4x - 4 y = 64
ie. x - y= 64/4 = 16
Now x - y+16....(ii)
Put from (ii) into (i)
(y+16)2 + y 2 =640
i.e y2 + 256 + 32 y + y2 = 640
i.e 2y2 + 32 y - 384 = 0
i.e y2 + 16 y - 192 =0
Now solve this quadratic to get y . Then put in (ii) to get x
