Coordinates to Find Perimeter and Area Practice Test

$\frac{1}{2}\left|1(0-4)+5(4-2)+3(2+2)+(-1)(-2-0)\right|$

$\sqrt{(5-1)^2+(0+2)^2}+\sqrt{(3-5)^2+(4-0)^2}+\sqrt{(-1-3)^2+(2-4)^2}$

$\sqrt{(5-1)^2+(0+2)^2}+\sqrt{(3-5)^2+(4-0)^2}+\sqrt{(-1-3)^2+(2-4)^2}+\sqrt{(1+1)^2+(-2-2)^2}$

$(5-1)+(4-0)+(3-(-1))+(2-(-2))$
