Question

Find the distance between the points (8,9) (-7,4)

Answer 1

use the formula ✓(x2-x1)²+(y2-y1)²

Answer 2

Using distance formula :-

$distance \: = \sqrt{ {( - 7 - 8)}^{2} + ( 4 - 9 } \\ \\ distance \: = \sqrt{ {(15)}^{2} + {( - 5)}^{2} } \\ \\ distance = \sqrt{225+50} \\ \\ distance = \sqrt{250}$

= √250

= √(25*10)

= 5√10
