Question

The distance between the two points P(1,2) and Q(3,4) is

Answer 1

Answer:

Step-by-step explanation:

P={1,2}

Q={3,4}

Distance=$\sqrt{{(x2-x1)^2-(y2-y1)^2}$

             =$\sqrt(3-1)^2-(4-2)^2}$

             =$\sqrt{(2)^2-(2)^2$

            =0 units

Answer 2

The distance between the points is 2√2.

The calculations are as follows:

Using Distance Formula

°•°Distance b/w two points=√(x2-x1)^2+√(y2-y1)^2

for distance b/w P and Q where p(1,2) and Q(3,4)

PQ=√(3-1)^2 +√(4-2)^2

PQ=√4+√4

PQ=√8

PQ=2√2
