Question

Find the distance between the points given. (2, 2) and (5, 5)

Answer 1

3
`√(2)`

Explanation:

Calculate the distance using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (2, 2) and (x₂, y₂ ) = (5, 5)

d =
`√((5-2)^2+(5-2)^2)`

=
`√(3^2+3^2)` =
`√(18)` = 3
`√(2)` ← exact value
