Question

Find the area of the triangle formed by points (-10,-4),(-8,-1)and(-3,-5)

Answer 1

Answer:

28.5

Step-by-step explanation:

Given (-10,-4)(-8,-1)(-3,-5)

area of triangle formula

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

take -10 as x1,-4 as y1,-8 as x2,-1 as y2,-3 as x3,-5 as y3

than

1/2|-10 (-1-(-5))+(-8)(-5-(-4))+(-3)(-4-(-1))|

1/2|-10 (-1+5)+(-8)(-5+4)+(-3)(-4+1)|

1/2|-10 (+4)+(-8)(-1)+(-3)(-3)|

1/2|40+8+9|

1/2|57|

|28.5|

so answer is

28.5
