Use the distance formula to find the distance between each pair.
D%5B1%5D=sqrt%28%28-4-0%29%5E2%2B%281-3%29%5E2%29=sqrt%2816%2B4%29
D%5B2%5D=sqrt%28%28-4-3%29%5E2%2B%281-%28-2%29%29%5E2%29=sqrt%2849%2B9%29
D%5B3%5D=sqrt%28%280-3%29%5E2%2B%283-%28-2%29%29%5E2%29=sqrt%289%2B25%29
Complete that calculation.
Then,
P=D%5B1%5D%2BD%5B2%5D%2BD%5B3%5D
