I'm a bit stuck on this. I need an explanation and solution

Question

A transformation of ABCD is represented by this matrix operation.

-Describe the transformation in words

-Determine the coordinates of A' B' C' D'

Answer 1

I take it that A = (1, 2), B = (4,1), etc and A' = (2.5, 5), B' = (10, 2.5), etc

This is a dilation with scale factor 2.5.
