Answer:

  • 4 units

--------------------

We are given that rectangles ABCD and PQRS  are similar.

Also given that:

  • AB = 25 units,
  • PQ = 5 units,
  • AD = 20 units

Use equal ratios of corresponding sides:

  • AB / PQ = AD / PS

Substitute values and find the length of PS:

  • 25 / 5 = 20 / PS
  • 5 = 20/PS
  • PS = 20/5
  • PS = 4

Therefore, the measure of PS is 4 units.
