Whats the area of this figure: (-5,3)(0,-1)(4,4)

The given figure is a triangle.

Let points be P(-5,3), Q(0,-1) and C(4,4)

Using coordinate geometry we can determine the area by:

Area = Mod ()

Px, Qx, Rx refers to x coordinates of point P, Q and R, respectively

Py, Qy, Ry refers to y coordinates of point P, Q and R, respectively

Substituting the values in the area formula:

Area = Mod ()

⇒ Area = Mod (

⇒ Area = Mod ()

⇒ Area = 20.5 sq. units
