Question

What is the distance between `(18,5)` and `(7,4)`?

Answer 1

Distance `=sqrt(122`

Explanation:

The coordinates are :
`(18,5) =color(blue)(x_1,y_1`
`(7,4) = color(blue)(x_2,y_2`

the distance is found using formula
distance `=sqrt((x_2-x_1)^2 + (y_2-y_1)^2`

`=sqrt((7-18)^2 + (4-5)^2`

`=sqrt((-11)^2 + (-1)^2`

`=sqrt((121 + 1)`

`=sqrt((122)`
