Question

If BC : QR = AC : PR what is the length of QR ?
​

Answer 1

by the image sides of ∆pqr = 2xsides of ∆abc

then QR = 14cm.

Answer 2

Answer:

Step-by-step explanation:

BC : QR = AC : PR

Or BC/QR =AC/PR

Then ΔABC ~ ΔPQR

thus its sides are proportional

BC/QR=AB/PQ

7/y=4/8=1/2

y=7*2=14

Thus QR=14 cm
