Answer:

A

Explanation:

calculate the length of BD using the distance formula

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

let (x₁, y₁ ) = B (- 4, 2 ) and (x₂, y₂ ) = D (2, 6 )

substitute these values into the formula for d

AB =
√((2-(-4))^2+(6-2)^2)

=
√((2+4)^2+4^2)

=
√(6^2+16)

=
√(36+16)

=
√(52)

=
√(4(13))

=
√(4) ×
√(13)

= 2
√(13)
