Question

the distance between the points A(√3 + 1; √2 - 1) and (√3 - 1; √2 + 1) is
a.√3
b.2√3
c.√2
d.2√2

Answer 1

Answer:

Option(D)

Step-by-step explanation:

Given points are A(√3 + 1, √2 - 1) and (√3 - 1, √2 + 1)

Distance between points d = √(x₂ - x₁)² + (y₂ - y₁)²

=> √(√3 - 1 - (√3 + 1)²)) + (√2 + 1 - (√2 - 1)²)

=> √(-2)² + 2²

=> √4 + 4

=> √8

=> 2√2

Hence, the distance is 2√2
