Heya !!
Here's your answer.. ⬇⬇
♦ Given :- Let The triangle be ∆ABC and ∆PQR.
In ∆ABC,
Base of ∆ABC is BC = 9cm
Altitude of ∆ABC is AE = 5cm
In ∆PQR,
Base is QR = 10cm
Altitude is PM = 6cm
♦ To Find :- Ratio of Area of ∆ABC and ∆PQR
♦ Solution :-
Hence, Ratio of Area of ∆ABC to ∆PQR is 3:4

Answer:
Let ABC and PQR be two right triangles with AB ⊥ BC and PQ ⊥ QR.
Given: BC = 9, AB = 5, PQ = 6 and QR = 10.
AreaABC
AreaPQR
ACBC
PQQR
Area(△ABC)Area(△PQR)=12×AC×BC12×PQ×QR
=
12×5×912×6×10
=
34
Hence, Ratio of Area of △ABC : Area of △PQR =
3: 4.
