Rectangle ABCD with coordinates A(1, 1), B(4, 1), C(4, 2), and D(1, 2) dilates with respect to the origin to give rectangle A'B'C'D'. If = 6, what is the scale factor of the dilation?
I have attached a screenshot with the complete question.
Answer: dilation factor is 2
Explanation: First, we will need to find the distance of AB as follows: distance = [tex] \sqrt{(x2 - x1)^2 + (y2 - y1)^2} [/tex] AB = [tex] \sqrt{(4-1)^2 + (1-1)^2} [/tex] AB = √9 = 3 units
Dilation can be represented as follows: A'B' = k * AB where k is the dilation factor
We are given that: A'B' = 6
We can note that: A'B' = 2 * AB Therefore, the dilation factor is 2.
