Find the area of the given triangle using the following formula:

Area of the triangle is 31

Step-by-step explanation:

Looking at the figure, we get

a = 3

b = 4

c = -2

d = 7

e = -1

f = -6

Now the formula to calculate the are of triangle is:

Now, putting values of a, b,c,d,e and f and finding determinant first

So, area of the triangle is 31

it is true
