What is the area of a triangle with the coordinates (-4,14) (10,0) (-14,-10)

You can use Heron Formula in the calculator to output the result, but i still show you the steps on paper thro

lengths of the 3 lines: / sqrt{392}, / sqrt{676}, / sqrt{676}

s = (/sqrt{392} + / sqrt{676} + / sqrt{676}) / 2=35.89949494

area = / sqrt{s (s - / sqrt{392}) (s - / sqrt{676}) ^2 } = 238
