Question

. Find the area of the triangle whose vertices are
(1) (2, 3) (-1,0), (2,-4)​

Answer 1

Hi mate here is your answer:-

Step-by-step explanation:

Question:--- Find the area of the triangle whose vertices are

(2, 3), (-1, 0), (2, -4)

Answer:---

Given (2, 3), (-1, 0), (2, -4)

Let us Assume A(x1, y1) = (2, 3)

Let us Assume B(x2, y2) = (-1, 0)

Let us Assume C(x3, y3) = (2, -4)

Then by area of triangle

Now,

Area of given triangle

=1/2[{2(0-(-4))}+(-1){(-4-3)+2(3-0)}]

=1/2{8+7+6}

=21/2 Square units

Hope it helps you ❣️❣️
