Answer:We are going to define the following variables:
A: Area of the original figure.
k: scale factor.
We have that the area of the new figure (reduced or enlarged, depends on the value of k) is:
A '= k ^ 2 * A
Example: rectangle of dimensions (2) * (3) A factor of k = 2 is extended. Find the new area.
The original area is:
A = (2) * (3) = 6
The new area will be:
A '= (2 * 2) * (2 * 3) = 4 * 6 = 24
Or equivalently:
A '= k ^ 2 * A
A '= (2) ^ 2 * (6) = 4 * 6 = 24
I don’t understand the question
