Question

5. AABC = ARQP, a:b:c = 2:3:4 and perimeter of ARQP is 45 cm, where
BC = a, CA = b, AB = c. If PQ = r, QR = p and RP = q, find the
length of p, q, r.​

Answer 1

Answer:

ANSWER

Given,

BC:CA:AB=1:2:3

Let BC be x.

Then, CA=2x,AB=3x

Since, the triangles ABC and PQR are the similar.

Therefore,

QR=BC=x

PR=AC=2x

Therefore, the required ratio

PR

QR

=

2x

x

PR

QR

=

2

1

Hence, this is the answer.
