Write a python program that prompts the user to enter the three points $(x1,y1),(x2,y2),$ and $(x3,y3)$ of a triangle and displays its area. The formula for computing the area of a

triangle is:

$s=\frac{\text{s}\text{i}\text{d}\text{e}1+\text{s}\text{i}\text{d}\text{e}2+\text{s}\text{i}\text{d}\text{e}3}{2}$

area $=(s(s-$ side$11)(s-$ side$2)(s-$ side$3){)}^{0\mathrm{.}5}$
