Since the area of square is 784cm^2
so its side will be √784=28cm
Since the area of circles is max
2xdia will be equal to a side
So 2(2r)=28
So r=7cm
circumference = 2πr=14π cm
= 14 * 22/7 cm
= 44 cm

Answer:
44 cm.
Step-by-step explanation:
Area of square =
Since we are given that the area of square is
So,
Now we are given that Four equal sized maximum circular plates are cut off from a square
So, Diameter of all the plates will be same
Let the diameter of plates be d
Diameter of 2 circular plates = Side of square
So,
So, diameter of each plate is 14 cm
So, Radius of each plate = = =7 cm.
Circumference of plate =
=
=
Hence the circumference of the circular plate is 44 cm.
