Answer 2

Answer:

2√(a²+b²) units

Step-by-step explanation:

Hii mate ^_^

We know that,

Distance between two points (a,b) and (c,d) = √[(a-b)²+(c-d)²]

Here,

Given two points (a,b) and (-a,-b),

So,

Distance between (a,b) and (-a,-b) = √[ (a-(-a))² + (b-(-b))²]

                                                         = √[(2a)²+(2b)²]

                                                         = √(4a²+4b²)

                                                         = √[4(a²+b²)]

                                                         = √4 × √(a²+b²)

                                                         = 2√(a²+b²)

Hence,

Distance between the two points (a,b) and (-a,-b) = 2√(a²+b²) units
