Find the distance between the pairs of points: (2, –1, 3) and (–2, 1, 3)

#### 1 Answer

##### Solution :-

Let P be (2, – 1, 3) and Q be (– 2, 1, 3)

So here,

x1 = 2, y1 = – 1, z1 = 3

x2 = – 2, y2 = 1, z2 = 3

Distance PQ =

$$\sqrt{(-2 – 2)^2 + (1 – (-1))^2 + (3 – 3)^2}$$

$$\sqrt{(-4)^2 + (2)^2 + (0)^2}$$

$$\sqrt{16 + 4 + 0}$$

$$\sqrt{20}$$

$$2\sqrt{5}$$

The required distance is $$2\sqrt{5}$$ units.
