Question

Compute the distance between the two points.

(-3, 4) and (21, 11)
Os 19.3
o 12.2
0 25

Answer 1

Answer: 25

Explanation:

`x_(1)` = -3

`x_(2)` = 21

`y_(1)` = 4

`y_(2)` = 11

The formula for calculating distance between two points is given as :

D =
`\sqrt{(x_(2)-x_(1)) ^(2)+(y_(2)-y_(1)) ^(2)}`

Substituting the values , we have

D =
`\sqrt{(21-[-3])^(2)+(11-4)^(2)}`

D =
`\sqrt{(21+3)^(2)+(11-4)^(2)}`

D =
`\sqrt{(24)^(2)+(7)^(2)}`

D =
`√(625)`

D = 25
