Rectangle PQRS is rotated 90 clockwise about the origin what are the coordinates of R
nikitadnepr [17]

\boxed{R'(1,-5)}

<h2 /><h2>Explanation:</h2>

When rotating a point (x,y) around the origin in clockwise direction, you must always swap the x- and y-coordinates and then multiply the new x-coordinate by -1. In a mathematical language this is as follows:

(x,y)\rightarrow(y,-x)

Since you haven't provide any diagram, I'll use the attached figure below, From here, we have the following points:

P(2,3) \\ \\ Q(5,3) \\ \\ R(5,1) \\ \\ S(2,1)

So according to our rule, by rotating PQRS 90 degrees clockwise about the origin, we get the new points R':

\boxed{R'(1,-5)}
