Question

1. Find the area of the triangle whose vertices are (-5,-1),(3,-5),(5,2)
​

Answer 1

= 1/2 {35 + 9 + 20 }

= 64/2

= 32 square units

Answer 2

Answer:

32sq.units

Step-by-step explanation:

So first of all here we are given 3 vertices.

Let us consider all 3 verticess of the triangle.

A(x1, y1) = (-5, -1)

B(x2, y2) = (3, -5)

C(x3, y3) = (5, 2)

Area of triangle formula:

1/2 [x1(y2-y3)]+[x2(y3-y1)]+[x3(y1-y2)]

Area for given triangle:

1/2(-5
