Answer:

23.3

(or $4\sqrt{34}$ (let me know if you wanted this one and is you want it explained) lol)

Step-by-step explanation:

To find the length of the fence, use the Pythagorean theorem because, if you cut a rectangle diagonally, you will create two right triangles, and this formula only works with right triangles:

$a^{2} +b^{2} =c^{2}$

Insert values:

$12^{2} +20^{2} =c^{2}$

Solve for c:

Evaluate exponents

$144+400=c^2$

Simplify addition

$544=c^2$

Find the square root of both

$\sqrt{544} =\sqrt{c^2}\\\\\sqrt{544} =c\\\\23.324=c\\\\c=23.3$

The fence needs to be approximately 23.3 m.

This is the well known Monty Hall problem.

You have more chances of winning by switching doors.

Let A,B,C denote the events "The ferrari is behind A" and so on
Let HA,HB,HC denote the events "The host opens A" and so on

By Baye's formula, $P(B)_{HC}=\frac{P(HC)_BP(B)}{P(HC)}=\frac{\frac{1}2\cdot\frac{1}3}{\frac{1}2}=\frac{1}3$ whereas $P(A)_{HC}=\frac{P(HC)_AP(A)}{P(HC)}=\frac{1\cdot\frac{1}3}{\frac{1}2}=\boxed{\frac{2}3}$ !!
