`Delta ABC ~ Delta PQR` and `ar(DeltaABC)=4ar(DeltaPQR)` IF `BC=12cm` then find `QR`

Let DeltaABC~DeltaPQR and (ar (DeltaABC))/(ar (DeltaPQR))=4/(25) . If AB=12cm, BC = 8cm and AC=10cm then QR is equal to

If DeltaABC~DeltaPQR,(ar(DeltaABC))/(ar(DeltaPQR))=16/9 ,AB=2cm and AC= 12 cm, then find the value of PR.

Let DeltaABC~DeltaQPR and (ar(DeltaABC))/(ar(DeltaPQR))=9/(16) . If AB=12 cm , BC=6 cm and AC=9 cm , then PR is equal to :

DeltaABC~DeltaPQR , AB:PQ=3:4 then ar DeltaABC : ar DeltaPQR =……

If DeltaABC~DeltaQRP,(ar(DeltaABC))/(ar(DeltaPQR))=9/4 ,AB=18 cm and BC=15 cm, then PR is equal to

(B) Solve any four of the following subquestions : Delta ABC ~ Delta PQR, A (Delta ABC) = 9 cm^(2) and A ( DeltaPQR) = 16 cm^(2) . If BC = 2.1 cm then find the length of segment QR .

If Delta ABC~Delta QRP, (ar (Delta ABC))/(ar (Delta PQR))=(9)/(4), AB=18 cm, and BC= 15 cm, then PR=?

If DeltaABC~DeltaQRP,(ar(DeltaABC))/(ar(DeltaPQR))=9/4 , AB= 18 cm and BC= 15 cm, then PR is equal to
