​

Answer 1

Answer:

PQ- 20 here is the Answer

Answer 2

Answer:

Step-by-step explanation:

Psq is alright angle triangle

16^+12^2= pq^2

256+144=400

Pq=20

Perimeter of pqr=20+48+52=120

Semiperemeter=120/2=60

Area of pqr=(60×(60-52)×(60-48)×(60-20))^1/2

=(60×8×12×40)^1/2

=(10×6×4×2×3×4×4×10)^1/2

=10×6×4×2

=480

Area of pqs=1/2×12×16

=96

Therefore area of the shaded part is 480-96=378sq.cm.
