Question

Find the distance between the points (2,3), (4,1).

Answer 1

Determine the total surface area of the cube [I.e the combine area of six squares together

Answer 2

d ≈ 2.83 units

Explanation:

calculate the distance d using the distance formula

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

let (x₁, y₁ ) = (2, 3 ) and (x₂, y₂ ) = (4, 1 )

substitute these values into the formula for d

d =
`√((4-2)^2+(1-3)^2)`

=
`√(2^2+(-2)^2)`

=
`√(4+4)`

=
`√(8)`

≈ 2.83 units ( to 2 decimal places )
