THE POINTS OF INTERSECTION ARE (10,0),(0,10),(-10,0) & (0,-10).
THE DISTANCE BETWEEN ANY TWO OF THESE POINTS IS
SQUARE OF DISTANCE =10^2 + 10^2
=100 + 100
=200
THEREFORE DISTANCE = √(200)
=√(5 * 5 * 2 * 2 * 2)
= 10√2
DISTANCE BETWEEN ANY TWO POINTS WILL BE 10√2 UNITS.
but the answer is given as 20. how its possible
