Answer:
A. 22 cm
Step-by-step explanation:
By the Thales Theorem we know that: If we have two parallel straight lines and they cut other two ones, for example lines of a triangle then they produce proportional segments, which means:
RP is proportional to PT and SQ is proportional to QT, we can express that as:
RP/PT=SQ/QT
And we have:
RP is 8 cm
PT is 16 cm
SQ is 11 cm
Then:
8/16=11/QT
We have to calculate QT:
QT= (16*11)/8 =22cm
