Answer 1

area of first triangle= 1/2*9*5

=45/2...............1

area of second triangle = 1/2*10*6

=30....................2

ratio= 45/2/30/

=45/60

=3/4

ratio =3:4

Answer 2

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.

∴A(△ABC)/A(△PQR)

=AB×BC/PQ×QR

=5×9/6×10

=3/4
