Area of the triangle defined by the coordinates (-3, -4), (-7, 0), and (-3, 4).
1 answer:
Here: (Aₓ, Ay) = (-3,-4), (Bₓ, By) = (-7,0), (Cₓ, Cy) = (-3, 4) Now, Formula of area of triangle is: area = [Aₓ(By - Cy) + Bₓ(Cy - Ay) + Cₓ(Ay - By)] / 2 Substitute the values in to the expression, area = [-3(0-4) - 7(-4-(-4)) - 3(-4-0)] / 2 area = [-3(-4) -7(0) -3(-4)] / 2 area = [12-0+12] / 2 area = 24 / 2 area = 12Final answer would be 12 units. Hope this helps!
