Question

plz give the answer step by step ​

Answer 1

Answer:

this can be answered by using the following formula (|X1(y2-y3)+x2(y3-y1)+x3(y1-y2)|

Step-by-step explanation:

here a=(1,2)

b=(3,4)

c=(2,4)

so X1=1; x2=3;. x3=2

y1=2;. y2=4;. y3=4

now substitute the values in the formula

|1(4-4)+3(4-2)+2(2-4)|

|1(0)+3(2)+2(-2)|

|0+6-4|

6+4

=10
