Answer:
Step-by-step explanation:
Let the blue point is located at the origin.
Therefore, coordinates of the vertices of the given triangle ABC will be,
A(2, 1), B(2, -1) and C(3, -1)
Rule for the dilation of a point (x, y) by a scale factor 'k' will be,
(x, y) → (kx, ky)
By applying this rule, coordinates of the image points of the vertices will be,
A(2, 1) → A'(2k, k)
→ A'(6, 3) for (k = 3)
B(2, -1) → B'(6, -3)
C(3, -1) →C'(9, -3)
Pls. see attachment.
The perimeter of the triangle is 146.
