Calculate the area and centroid of a triangle
with vertices at (1,1), (2,3), and (4,5)
Calculate the Area:
Area =
|x1(y2 - y3) + x2(y3 - y1) + x3(y1 - y2)|
2
Area =
|1(3 - 5) + 2(5 - 1) + 4(1 - 3)|
2
Area =
|1(-2) + 2(4) + 4(-2)|
2
Area =
|-2 + 8 + -8|
2
Area =
|-2|

Area = 1
Centroid Formula:
x1 + x2 + x3
