IMHO: RT = sqrt 58
correct?

My rationale is to create a bigger square that embraces the given one. The points P, Q, R, and S touch the sides of the bigger square but not bisect them! They share each side of the bigger square by 4:3; this fact is clear from the information that PT is perpendicular to QT, QT=3, and PT=4.

Further, you have to see that the right vertical side of the bigger square is 7, and the bottom one is shared 4:3, maiking it possible to find RT via the right triangle (7-3-RT).

RT^2=7^2+3^2
RT=sqrt 58.

The trick is that a small square is inscribed into a bigger one, not bysecting the sides of the latter, but splitting them into a 4:3 proportion.

Moscow is enormous now. It is a different country if you compare it with other Russia. Moscow is one of the richest cities of the world, and one of the most expensive ones.
