Triangle perimeter and area $($JavaScript$)$

A triangle's three vertices can be defined with three $($x$,$ y$)$ coordinates. Ex: The figure below shows a triangle with vertices $(1,0),(2,4),$ and $(4,3).$

Write two functions: trianglePerimeter$()$ and triangleArea$().$ Both functions have six integer parameters representing the coordinates of a triangle's three vertices.

The trianglePerimeter$()$ function should calculate the length of each side using the distance formula below. Then the function should return the sum of the three sides' length.

Ex: The function call trianglePerimeter$(1,0,2,4,4,3)$ returns $10\mathrm{.}601814290236735,$ the sum of the three sides' length:

Distance from $(1,0)$ to $(2,4)=4\mathrm{.}1231056256177$

Distance from $(2,4)$ to $(4,3)=2\mathrm{.}2360679774998$

Distance from $(4,3)$ to $(1,0)=4\mathrm{.}2426406871193$

The triangleArea$()$ function should calculate and return the triangle's area using the following equation:

x$1($Y$2-)+$ x$2(-1)+($Y$1-$ Y$2)|/2$

Ex: The function call triangleArea$(1,0,2,4,4,3)$ returns $|1(4-3)+2(3-0)+4(0-4)|/2=|1+6+-16|/2=|-9|/2=4\mathrm{.}5.$

Hint: The JavaScript Math object has methods for squaring numbers, calculating a number's square root, and finding a number's absolute value.

Need to know what code to write the TODO area below

function trianglePerimeter$($x$1,$ y$1,$ x$2,$ y$2,$ x$3,$ y$3)\{$

$//$ TODO: Write your code here

$\}$

function triangleArea$($x$1,$ y$1,$ x$2,$ y$2,$ x$3,$ y$3)\{$

$//$ TODO: Write your code here

$\}$

console.log$("$Testing trianglePerimeter$()...")$;

let perimeter $=$ trianglePerimeter$(1,0,2,4,4,3)$;

console.log$("$Perimeter $="+$ perimeter$)$;

console.log$("$Testing triangleArea$()...")$;

let area $=$ triangleArea$(1,0,2,4,4,3)$;

console.log$("$Area $="+$ area$)$;

$//$ Do NOT remove the following line:

export $\{$ trianglePerimeter, triangleArea $\}$;
