Question

Find the area of triange whose vertices are (-5,-1) (3,-5) (5, 2) ​

Answer 1

Given points are (-5,-1) (3,-5) (5, 2)

x1 = -5. y1 = -1

x2 = 3. y2 = -5

x3 = 5. y3 = 2

Area of triangle =

$= \frac{1}{2}(x1(y2 - y3) + x2(y3 - y1) + x3(y1 - y2))$

put it in it u will get ur ans

sry for it but try by urself
