Answer:
5 units
Step-by-step explanation:
Draw an imaginary right - angled triangle.
One side will be 8 - 4 = 4 units
Another side with be 5 - 2 = 3 units
By Pythagoras Theorem, to find hypotenuse / distance between two points (works for right - angle triangles),
3² + 4² = d²
d² = 25
d = ±√5
d = 5 or -5 (rejected, as value of distance cannot be negative)
