Question

The vertices of D ABC are (-2, 1), (5, 4) and (2, -3) respectively. Find the area of triangle.

Answer 1

Answer:

-20cm or 20 cm

Step-by-step explanation:

use the formula for the area of the triangle below

Area of Triangle =  1/2   (x1(y2−y3)+x2(y3−y1)+x3(y1−y2))

where (-2,1) is x1,y1  5,4 is x2 y2 and x3y3

Answer 2

you can do it by the formula given in std 10 textbook in the chapter coordinate geometry. when we open the module the negative sign changes to positive
