Question

13. If AABC - APQR, perimeter of ABC =
32 cm, perimeter of PQR = 48 cm and
PR = 6 cm, then the length of AC is equal
to......​

Answer 1

Step-by-step explanation:

Aloha !

By comparing both given triangles.

AC=PR

PR=6 (given)

So,

AC=6 cm.

Answer 2

Step-by-step explanation:

$\huge{ { \red{answer}}}$

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 

AC=(6×32)/48

AC=192/48

AC=4

therefore AC = 4cm
