Explanation:

Given,

PS⊥RQ and QT⊥PR

Also, RQ=6,PS=6 and PR=12

Using RQ as base and PS as corresponding height,

∵ Area if triangle = 1/2 ×Base×Height

⇒ ΔPQR= 1/2 ×RQ×PS

⇒ ΔPQR= 1/2 ×6×6

⇒ ΔPQR=3×6=18 .............(i)

Now, Again using PR as base and QT as corresponding height,

Area of ΔPQR= 1/2 ×12×QT.........from eq (1)

⇒18=6×QT

⇒QT×6=18⇒QT=

6

18

=3

Hence, QT=3 units
