Question

Choose all that correctly identify the area of the triangle given the coordinates of its vertices. A(1, 2), B(4, 5), C(4, 0) area = 9.5 units2 A(1, 1), B(5, 2), C(3, 5) area = 7 units2 A(−3, 1), B(1, 3), C(2, −4) area = 12 units2 A(−3, −1), B(−5, −4), C(−2, −5) area = 5.5 units2

Answer 1

A(1, 1), B(5, 2), C(3, 5)

area = 7 units^2

&

A(−3, −1), B(−5, −4), C(−2, −5)

area = 5.5 units^2
