Triangle abc has vertices at a(-2,1), b(-2,-3), and c(1,-2). what is the area of the triangle? a 18 square units b 9 square units c 6 square units d 12 square units

Option C. 6 square units

Step-by-step explanation:

we know that

Heron's Formula is a method for calculating the area of a triangle when you know the lengths of all three sides.  

Let  

a,b,c be the lengths of the sides of a triangle.  

The area is given by:

where

p is half the perimeter

p=

we have

Triangle ABC has vertices at A(-2,1), B(-2,-3), and C(1,-2)

the formula to calculate the distance between two points is equal to

step 1

Find the distance AB

step 2

Find the distance BC

step 3

Find the distance AC

step 4

Find the half perimeter p

p=

Find the area

fist on the left goes with the third on the right. second on the left goes with the fourth on the right. third on the left goes with the second on the right. the fourth on the left goes with first on the right

answer: 0,6

step-by-step explanation:

this would make it the y intercept.
