Question

Find the distan between pairs of points (2,3) (4,1)​

Answer 1

2√2 units

Step-by-step explanation:

Distance = √ (2-4)^2 + (3-1)^2

= √ 4 + 4

= √ 8

= 2√2 units

Answer 2

Step-by-step explanation:

ANSWER:-

For this , we need to use distance formula.

From the Chapter - Coordinate geometry.

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

Where, in this question,

• x1 is 2
• x2 is 4
• y1 is 3
• y2 is 1

So, we need to place it.

Let's Do!

$\sqrt{ {(2 - 4)}^{2} + {(3 - 1)}^{2} }$

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

$\sqrt{4 + 4}$

$= \sqrt{8}$

$= 2 \sqrt{2}$

So, distance between the points is $= 2 \sqrt{2}$ units. is the answer.

Note:-

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

• This formula, is what we need to remember.
