Another easy challenge for you.
Write a program or function that takes the input, which contains 3 pairs of x- and y-coordinates and calculates the area of the triangle formed inside them. For those who can't remember how to calculate it, you can find it here.
1,2,4,2,3,7 # input as x1,y1,x2,y2,x3,y3 7.5 # output
See it at Wolfram Alpha
- The input will be six base 10 positive integers.
- You may assume the input is in any reasonable format.
- The points will always form a valid triangle.
- You can assume the input is already stored in a variable such as
- The shortest code in bytes wins!
Edit: To avoid any confusion I've simplificated how the input should be dealt without jeopardizing any of the current codes.
Remember that the your program/function must output a valid area, so it can't give a negative number as output
