Answer:

She would need #17.20465# meters (I wouldn't suggest doing it with less than #18# meters).

Explanation:

Note: you forgot to mention how much wire Lorendo has.

The amount of wire required (ignoring wire required to wrap around a ground stake and the top of the pole)
is the hypotenuse of a triangle with arms #14# and #10# meters.

Using the Pythagorean Theorem (and a calculator) this value is
#color(white)("XXX")17.20465# meters.
