Question

The area of triangle with vertices at (+4,-1) , (1,2),(4,-3) is​

Answer 1

Answer:

3 units

Step-by-step explanation:

FORMULA➡️ Area of triangle= ½[y1(x2-x3)+y2(x3-x1)+y3(x1-x2)

Area of = ½[4(2-(-3))+1(-3-(-1))+4(-1-2)]

=½[4(2+3)+1(-3+1)+4(-1-2)]

=½[4(5)+1(-2)+4(-3)]

=½[20-2-12]

=½[6]

=3 units
