1. The vertices of the quadrilateral after a dilation with scale factor 2.5 are A’ = (0, 0), B’ = (0,7.5), C’ = (12.5, 7.5) and D’ = (12.5, 0)

   How to determine the vertices of the quadrilateral after a dilation with scale factor 2.5?

   The coordinates of the quadrilateral ABCD are given as:

   A(0,0), B(0,3), C(5,3), and D(5,0)

   When dilated by a scale factor of 2.5, we have the following equation

   A’ = A * 2.5

   So, we have:

   A’ = (0,0) * 2.5

   A’ = (0, 0)

   B’ = (0,3) * 2.5

   B’ = (0, 7.5)

   C’ = (5,3) * 2.5

   C’ = (12.5, 7.5)

   D’ = (5,0) * 2.5

   D’ = (12.5, 0)

   Hence, the vertices of the quadrilateral after a dilation with scale factor 2.5 are A’ = (0, 0), B’ = (0,7.5), C’ = (12.5, 7.5) and D’ = (12.5, 0)
