To solve this, we can use the distance formula.
Distance =
[tex] \sqrt{(x2 - x1) {}^{2} + (y2- y1) {}^{2} } [/tex]
The two coordinates, (2,0) and (2,4) are (x1, y1) and (x2, y2) respectively.
We can now solve by substituting.
Distance=
[tex] \sqrt{ {(2 - 2)}^{2} + {(4 - 0)}^{2} } [/tex]
Solve the numbers.
[tex] \sqrt{16} [/tex]
= 4
Therefore, your answer is 4.
