Question

Let triangle abc and triangle qpr are similar and area of triangle abc/area of triangle pqr =1/16, if ab =12 cm,bc=6cm,ac=9cm then pq=?

Answer 1

Answer:

it's answer may be PQ=48

Step-by-step explanation:

by area theorem

area of ABC/area of PQR=

(AB/PQ)^2

so 1/16=(12/PQ)^2

1/16=144/PQ^2

PQ^2=144*16

PQ=√2304

PQ=48cm
