# What is the distance d between points a and b, where point a (3, 4) and b (1, 2)

**Solution:**

We will use the distance formula in order to find the distance between points a and b.

The distance between any two points A(a, b) and B(c, d) is given by,

d = **√** [(a - c)^{2} + (b - d)^{2}]

By substituting the points A(3, 4) and B(1, 2) in the above formula we get our required distance d.

⇒ **√** [(3 - 1)^{2} + (4 - 2)^{2}]

⇒ **√** [2^{2} + 2^{2}]

⇒ **√**8 = 2**√**2 units

Hence, distance d = 2**√**2 units.

## What is the distance d between points a and b, where point a (3, 4) and b (1, 2)

**Summary:**

The distance d between points A and B is 2**√**2 units.
