Question

Using determinants find the area of the triangle whose vertices are (1,2),(-2,3) and (-3,-4)

Answer 1

Answer:

Area of the triangle is "6"

Step-by-step explanation:

FORMULA for the area of the triangle :

x1*(y2-y3)+x2*(y3-y1)+x3*(y1-y2)

so, 1,2 is x1,y1 and -2,3 is x2 y2

and -3,-4 is x3,y3

Applying the formula

we get,

              = 1*(3- -4)+-2*(-4-2)+-3*(2-3)

              = -7+10+3

              = 6
