Question

The area of triangle whose vertices are (1,-1), (-4.6), and (-3, -5) is
(a) 21
(b) 32
(c) 24
(d) 25​

Answer 1

Answer:

C. 24

Step-by-step explanation:

Area of triangle = 1/2 | x1(y2 - y3) + x2(y3 - y1) + x3(y1 - y2) |

1/2 | 1(6 + 5) - 4(-5 + 1) - 3(-1 - 6) |

1/2 | 11 + 16 + 21 |

= 24
