Answer:
Step-by-step explanation:
RQ=6, PS=6 & PR=12..... (GIVEN)
AREA OF TRIANGLE =1/2x BASE x HEIGHT
AREA OF TRIANGLE =1/2 x 6 x 6
THERFORE, AREA OF TRIANGLE PQR =18 SQ UNITS.....(1)
ALSO, AREA OF TRIANGLE PQR =1/2 x PR x QT
THERFORE, 18 =1/2 x 12 x QT.... (FROM 1)
THEREFORE QT =18 DIVIDE BY 6
THEREFORE QT = 3
DONE.....
hope it helps

Answer:
Given:
PS ⊥ RQ
QT ⊥ PR
RQ = 6, PS = 6 and PR = 12
With base PR and height QT,
A(△PQR)=½×PR×QT
With base QR and height PS,
A(△PQR)=½×QR×PS
∴A(△PQR)/A(△PQR)=½×PR×QT/½×QR×PS
⇒1=PR×QT/QR×PS
⇒PR×QT=QR×PS
⇒QT=QR×PS/PR
=6×6/12
=3
Hence, the measure of side QT is 3 units.
