Answer:

here's your ans

In right-angled triangle PQR,

QR

2

=PQ

2

+PR

2

[by Pythagoras theorem]

⇒PR

2

=QR

2

−PQ

2

⇒PR=

17

2

−8

2

=15

Now, ar(ΔPQR)=

2

1

×PQ×QR

=

2

1

×8×15=60 cm

2

And ar(ΔPRS)=

2

1

×PR×SR

=

2

1

×6×15=45cm

2

Hence, ar(PQRS)=ar(PQR)+ar(PRS)

=60+45

=105 cm
