Question

find the distance between the pair of points.(-1;-2)(1;0)​

Answer 1

AnsWer :

2√2 unit

Given :

• P1 = (-1 , -2)
• P2 = (1 , 0)

To Find :

Distance between AB.

Solution :

Let point be,

• A( -1 , -2 )
• B( 1 , 0 )

We have Formula, (Distance Formula )

$\tt \dagger \: \: \: AB = \sqrt{ {(x_2- x_1)}^{2} + {(y_2 - y_1)}^{2} }$

So,

$\rule{90}1$

$\tt\longmapsto AB = \sqrt{{(1 + 1) }^{2} + {(0 + 2)}^{2} }$

$\tt \longmapsto AB = \sqrt{4 + 4}$

$\tt \longmapsto AB = \sqrt{8}$

$\tt\longmapsto AB = 2 \sqrt{2} \: unit.$

Therefore, the distance between pair of point be 2√2 Unit.

$\rule{200}3$
