Question

the distance between A (a+b , a-b) and
B (a-b , -a-b) is​

Answer 1

Answer:

d = √[(a-b-a-b) ² + (-a-b-a+b)²

= √(a²+ b²)

Answer 2

Answer:

√{ [ (a-b)-(a+b) ] ² + [( -a-b)-(a-b) ]² }

√ [ a-b-a-b ]² + [ -a-b-a+b ]²

√ (-b²) + (-a²)

√(b² + a²).

Step-by-step explanation:

Hence , this is the answer I guess.
