Question

if triangle ABC similar to triangle PQR perimeter of ABC =32cm , perimeter of. PQR=48 and PR=6cm then find the length of AC​

Answer 1

in triangle PQR and triangle ABC are congruent then AB equal to PQ and BC equal QR equal AC equal PR

perimeter of triangle ABC divided by perimeter of triangle PQR is equal AC ➗PR 32÷48=AC÷6 cross multiply AC=32×6÷48,AC=4cm,Ans...

Answer 2

Answer:

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
