Question

Determine the distance between (2,1) and (12,13)

Answer 1

`d = 15.620499`

Explanation:

To solve this question, we must use the following distance equation:

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

Plug your coordinates into the equation. Remember, a coordinate is denoted as (x, y).

`\sqrt{(12-2)^(2) + (13-1)^(2)}`

`\sqrt{(10)^(2) + (12)^(2)}`

`√(100+144)`

`√(244) = 15.620499`
