Question

In triangles ABC and PQR perimeter of ABC=20cm, perimeter of APQR-10cm and
PR=Sc. What is the length of AC?​

Answer 1

Step-by-step explanation:

Given: triangle ABC ∼ triangle PQR,  perimeter of triangle ABC = 32cm, perimeter of triangle PQR = 48cm and PR = 6cm 

since the y are similar, 

AB/PQ = BC/QR = AC/PR 

AC/PR = perimeter of triangle ABC/perimeter of triangle PQR 

AC/6 = 32/48 

AC*48 = 6*32 

therefore AC = 4cm
