To state the number required to multiply and find the area of the triangle.

Answer to Problem 3E
The area of the triangle is obtained by multiplying the value of determinant by
Explanation of Solution
Given information :
The given three points,
The value of the determinant is given as
The area of a triangle with vertices
Area
Here the symbol
Since, the value of the determinant is given as
Therefore,
The area of the triangle is obtained by multiplying the value of determinant by
