The vertex matrix form is
The new coordinates of
Explanation of Solution
Given information:
The coordinates of triangle
Calculation:
Consider the coordinates of triangle
The vertex matrix form is provided below,
According to the question the perimeter of the triangle is three times the original one.
Since, perimeter is the sum of the lengths of the sides of the triangle.
So, if perimeter is to be three times the original one, each coordinate needs to be three times.
For the new coordinates of the triangle the old vertex matrix must be multiplied with 3
Therefore,
Now, new coordinates are
Thus, the new coordinates of
