Answer:
The answer is 12
Step-by-step explanation:
∆ABC =
-4.5 3
3 -2
-3 2
-4.5 3
By doing multiplication like below
= (9.0 - 6 - (-9)) + (9 - 6 - (-9.0))
= 12 + 12
= 24
by dividing the answer by 2 cause of area of triangle is 1/2((a1*b2)-(a2*b3)-(a3*b1) + (a2*b1)-(a3*b2)-(a1*b3))
therefore,
= 1/2*24
= 12
The answer is 12
