Question

Please Help! In the figure below, triangle ABC is similar to PQR,as shown below:

What is the length of side PQ?

A. 100
B. 76
C.64
D.128

Answer 1

So triangle PQR is scaled at 4*triangle ABC
So if AB = 16 then PQ = 16*4 which is 64 so the third option

Answer 2

Triangle ABC is similar to PQR

AB/BC = PQ/QR

16/20 = PQ/80

PQ = 16 * 80 / 20

PQ = 64

Answer

C.64
