Question

find the distance between P(√a,√b) and Q(-√a,-√b)​

Answer 1

Answer:

Step-by-step explanation:

Given that,

P ( x1, y1) = ( √a, √b ) and Q (x2, y2) = ( - √a , - √b )

By using distance formula,

d = √ ( x2 - x1 )² + ( y2 - y1 )²

= √ ( - √a - √a )² + ( - √b - √b )²

= √( - 2√a )² + ( - 2√b )²

= √ 4a + 4b

= √4 ( a + b )

= 2√(a + b) units is the answer.
