Question

Find the distance between (1,2) (3,4)

Answer 1

Answer

√(3-1)^2+(4-2) ^2 =√(2) ^2+(2)^2=√8=2√2

Answer 2

Answer:

Applying distance formula

Under root.[ ( x2 - x1 ) ² + ( y2- y1 ) ² ]

Step-by-step explanation:

Here x 1 = 1

y1= 2

x2 = 3

y2 = 4

under root [ ( 3- 1 ) ² + ( 4-2) ²]

under root [ 2² + 2² ]

under root [ 4 + 4 ]

under root 8

2root2

i.e.

$2 \sqrt{2} \: units$
