Question

find the area of the points a(-5,7) b(-4,-5) c(-1,-6)​

Answer 1

Use area formula...

1/2 [x1(y2-y3) + x2(y3-y1) + x3(y1-y2)]

A(-5 take as x1 and 7 y1) like that another B and C you can take x2 y2, x3 y3

In that next area same take from B C and D... As same like before one...

And then add the both of the area and u will get the correct answer
