Question

Find the area of a triangle whose vertices have coordinates

Answer 1

means no getting can u pls explain it...

Answer 2

There's formula to find the area of triangle whose vertics have coordinate.
Suppose a triangle ABC,
Let coordinate of A be (x1,y1), B be (x2,y2)
And C be ( x3,y3)
Then formula for the area of triangle ABC is
1/2[x1 (y2-y3) + x2(y3-y1) + x3(y1- y2)]
